Points for Handling
Special Precautions............................................................ 10





Points for Handling 
10 
Special Precautions 
 
Use the inverter only within allowable ambient temperature range   
   (-10～
50°C). 
Since service life of the inverter is greatly affected by ambient temperature, use 
it within allowable temperature range. Also, observe the installation directions 
and conditions. (Refer to P.21) 
The inverter will be damaged if the power voltage is applied to its   
   output side.  
Applying power voltage to the output terminal U, V or W will damage the 
inverter. Check carefully for faulty wiring and operation sequence (commercial 
switching circuit, etc.). Never apply a voltage exceeding the allowable range. 
Never touch inside of the inverter during operation. 
Failure to do so could be extremely dangerous, since the inverter contains 
high-voltage circuit. Before making an internal check, be sure to wait at least 5 
minutes after turning OFF the inverter. Do not touch heat sink or braking 
resistor during operation as these parts are under high temperature. 
Radio interference  
The main circuit of the inverter contains a high-frequency harmonic component 
and may interfere with communicating equipments (such as AM radio) nearby. 
The severity of interference depends on the radio field strength and is hard to 
be eliminated completely. While it may be reduced by relocating radio antenna, 
using noise filter, housing the inverter in a metal box, or routing cables in 
conduit. (Please inquire separately.) 
Do not conduct insulation test between wires of the inverter.  
To measure insulation resistance between power cord and motor wires, please 
remove the cables connected to the inverter and conduct test with them. Do not 
conduct insulation test on the control circuits. However, insulation test can be 
performed between charging unit and the ground. 





Points for Handling 
11 
Do not use a magnetic contactor which is connected to power side or 
   load side of the inverter to start or stop the motor (inverter). 
Frequent ON/OFF switching on the power supply side can cause inverter 
malfunction. Also, do not conduct ON/OFF switching on load side during 
inverter operation, or it can cause fault trip of the inverter. Start or stop the 
motor by operating signals of the inverter only. 
Do not connect a power capacitor or a surge absorber to output side 
   of the inverter. 
Such device can damage the inverter, resulting in broken of capacitors and 
other parts. Remove it if connected. 
Do not use the inverter for load other than a motor or for a 1-phase 
   motor. 
If parameters are frequently written in, service life of built-in   
   non-volatile memory (EEPROM) of the inverter will be shortened.  
The maximum life of non-volatile memory (EEPROM) used in VF200 is 
100,000 times. Therefore, do not write in parameters frequently. 
Precautions for inverter's protection function 
The inverter integrates various protection functions such as stall prevention, 
current limiting and over-current shut-off. These protection functions are 
functions used to protect the inverter against the sudden abnormal conditions, 
instead of general control functions. 
Therefore, avoid using them in applications where they will be activated under 
normal conditions. 
Failure to do so may reduce the inverter's service life or damage the inverter. 
 
Always measure the output current, etc. with a meter, check the details of the 
fault trip memory, and confirm that operation conditions conform to the 
precautions and specifications are correct.

3.3.2 Precautions on Wiring Main Circuit 
 
■  Precautions on Wiring 
To avoid mistakes in wiring and operation, be sure to observe the following 
guides.(Failure to do so may damage the unit.) 
·Always connect the power source to input terminals (R/L1, S/L2, T/L3), and 
connect the motor to output terminals (U,V,W). 
·Use round crimp terminals with sleeve for power source and motor 
connections. Select crimp terminals according to wire sizes and screw sizes. 
·After wiring main circuit, confirm the tightening condition of terminals. 
·Main circuit must be wired prior to control circuit. Otherwise, re-tightening 
operation is not possible after control circuit wiring is completed. 
·When connecting directly to a transformer of large capacity (500 kVA or more), 
always install an AC reactor on the input side of the inverter. 
 
Note 1:  It is recommended to use teflon insulated wire (600 V, Class 2, 
allowable operating temperature up to 75 °C) for main circuit wiring. 
Note 2:  Use wires with larger diameter if the wiring distance is long. 
Note 3:  If the overcurrent trip of the circuit breaker is magnetic type, the 
device could become overheated due to higher harmonics. Use a 
load rate of 50% or lower in this case. 
Note 4:  If a circuit breaker for motor protection is in use, remove it.   
Note 5:  Always connect protective devices against overcurrent, short-circuit 
and current leakage on the input side. 
 
■  Precautions on Using Regenerative Brakes 
·When using regenerative brakes, set the parameter P019 to "0". Since the 
factory setting is "1", the brakes will not be activated. 
·Specifications for regenerative brakes are shown as follows. Carefully 
consider the operation conditions before using them. Note that the inverter 
could be damaged if a brake outside specifications is used. 
Max. duty factor (%ED): 5%  ·Max. operating time: 5 s  ·Max. torque: 100%

3.4.2 Common Precautions on Terminals for Control Circuit 
 
■  Precautions on Wiring 
·For wiring of terminals of control circuit, strip specified length of insulation 
coating before connecting. 
·Loosen the terminal screws and insert the wires from bottom of the terminal 
block, and tighten the screws to specified tightening torque. 
·Twist the strands of stripped wires, avoiding length variance. 
Also, do not solder them. 
·Any loose connection could cause wire to come off and lead to malfunction. 
Also, over-tightening could cause short-circuit due to screws and the unit 
broken, thus lead to malfunction. 
·Use shielded cables for all control signal lines and separate them from power 
lines or high-voltage circuits (20 cm or more). 
·Wiring length of control signal lines should be within 30 m. 
·Since input signals of control circuit are feeble, use dedicated terminals for 
feeble signals to avoid poor contact during contact input.

■  Wiring for PWM/Pulse input controlled Operating Frequency Mode (Terminal No.7, 8) 
·When parameter P087 is set to "1”, the operating frequency will be controlled 
by external PWM signal from PLC, etc.   
·When parameter P087 is set to "2”, the operating frequency will be controlled
by external pulse signal from PLC, etc.
·Terminal No.7 is the input terminal for changeover of frequency setting signal   
(SW4) (OFF: PWM/Pulse input signal, ON: controlled by the signal set in parameter P004), 
while terminal No.8 is the input terminal for PWM/Pulse input signal . 
·As for the transistor for PWM/Pulse input signal, please use one with maximum  
voltage rating over 50 V and maximum current rating over 50 mA.   
·In addition, to use PWM signal for operating frequency control, relevant 
settin
gs must be made to parameter P088 and P089. 
·Use pulse signal for operating frequency control, relevant settings must be 
made to parameter P174.
·When setting value is "1" or "2", the SW function for SW4(terminal No.7) and 
SW5(terminal No.8) will be forced to be used for controlling PWM/pulse signal only.

■  Wiring for Analog Signal Terminals (Terminal No.13 to 16, 24) 
·When parameter P004 is set to “2”,    frequency setting will be made through 
external potentiometer. 
·When using external potentiometer for frequency setting, select a 
potentiometer of “10 kΩ, 1/4 W or higher” rating. 
·When parameter P004 is set to “5” (4 to 20 mA) or “6” (0 to 20 mA), frequency 
setting will be made through analog current signal.   
·When using analog current signal (4 to 20 mA, 0 to 20 mA) for frequency 
setting, connect a resistor of “200 Ω, 1/4 W” rating. (Failure to do so may 
damage the inverter.) 
·If the unit version is Ver3.0 or later, a built-in 200 Ω resistor should be set 
between terminal No.24 and COM. If analog input signal of 4 to 20 mA / 0 to 20 
mA is used, external resistor connection can be eliminated by connecting 
terminal No.24 to No.14 or No.16.

・The STOP button is not designed for emergency stop 
purpose, so set a separate button for emergency
 stop.   
Failure to do so may result in injury.   
 
・The heat sinks and braking resistors are at high 
temperature, so do not touch them.   
Failure to do so could lead to burn. 
・The inverter can easily be switched to high speed from 
low speed, so confirm the allowable range of the motor 
and machine before making settings. 
Failure to do so could lead to injury.   
・Set separate holding brakes if required. 
Failure to do so could lead to injury.   
・Before turning on the power, check the following points again. 
1. Check if all wirings are correct or not again. 
 
Reversed wirings between power supply and load in 
 
particular could damage the inverter. 
2. Check if the voltage rating of the inverter matches 
  with power supply. 
3. 
Check if a phase-lead capacitor is connected to the motor. 
  Connection of phase-lead capacitor could result in 
  faults to the inverter and capacitor.

do not change parameter settings frequently.   
• If you change the parameters that cannot be set during operation when the 
operation signal is ON, “P.Err” will flicker in the display part first. And after 2 s, 
the display will return to parameter No. again. That’s to say, the inverter start
s 
operation without changing
 the parameter.

6.1.2 Setting and Changing Function Parameters 
During Operation 
 
 
If data is changed during operation, the motor and motor 
load may suddenly start/stop for the great fluctuation. 
(Please take measures to ensure personal safety.) 
Failure to do so may result in injury.   
 
For function parameters that can be changed during operation, refer to items 
marked with “” in “Changeable during Operation” of “6.2 Function Parameter 
List”.  
 
Setting Example 
Change the 1
st
 deceleration time from 5.0 s to 10.0 s (change setting value of 
parameter P002 from “5.0” to “10.0”) 
 
Controlling motor with current data 
1. Confirm operation status (For operation at 50.0 Hz).   
2. Press    button five times to select Function Setting 
Mode.  
(If a password is set beforehand, please enter it. Refer to 
parameter P150. ) 
3. Press    button once to change parameter No. to 
“P002”.  
4. Press    button to display setting value of parameter 
P002.  
(The display part is flickering.) 
5. Press    button to change the displayed value to “10.0”. 
(The display part is flickering.)

1. Press 
  button to set the value.   
2.
 
Press    button. (If the built-in memory setting mode is 
set to “conceal”, the inverter enters Operation Status 
Display Mode.) 
3.
 
Press    button to switch to Operation Status Display 
Mode.   
(If 
  button is not pressed, the display will not be 
switched.) 
 
 
• When “The 2
nd
 to 16
th
 Speed Frequency” of parameter P046 to P060 are set 
to “0000”, the inverter will enter 0V stop status.   
If parameters “P103: Bias Frequency Setting” and “P126: The 2
nd
 Bias 
Frequency Setting” are set to "0" or lower, the inverter will enter 0V stop status.   
If parameters “P104: Gain Frequency Setting” and “P127: The 2
nd
 Gain 
Frequency Setting" are set to “0000”, the inverter will enter 0V stop status.   
(The motor will start or stop when the data is changed or set to “0000”, so 
always ensure personal safety before operation.) 
• If you 
monitor parameters that cannot be set during operation when the 
operation signal is OFF, the setting values will flicker and then become 
changeable.

frequently by customer, thus making data modification easier. 
The number “1” to “10” can be allocated as custom parameter No. The 
allocated data will be written into built-in non-volatile memory of inverter. Even 
if the power is cut off, the data will still be held. (The built-in non-volatile 
memory of inverter can be written up to100,000 times. Therefore, do not 
allocate the function parameter No. frequently. ) 
 
■ Setting Example 
Allocate function parameter “P002” (The 1

indicator lights out.) 
 
 
 
9.3.2 The motor does not rotate. (When abnormality 
indicator lights up.) 
 
When abnormality indicators of P.114 to P.116 light up but the motor does not 
rotate, please check out the following two items.   
1. Check whether the abnormality occurs immediately after initial installation or 
during operation.   
2. Check whether the abnormality is caused by inverter failure (defect) or 
incorrect wiring and motor failure.   
 
for P.114 and P.116

10.1 Safety Precautions 
 
 
Wait at least five minutes after turning off the input 
power before starting maintenance and inspection 
work.  
Failure to do so may result in an electric shock. 
Maintenance, inspection and part replacement work 
must be done only by qualified persons.   
(Remove metal articles such as watch, bracelet(s) etc. 
before operation.) 
(Please use insulated tools.) 
Failure to do so may result in an electric shock or injury.
 
Employ an electrical engineering company to 
periodically tighten the terminal screws. 
Loose terminal screws could lead to overheating or fire.
 
 
10.2 Precautions on Inspection 
 
y To measure the insulation resistance between power supply cable and motor 
cable with megger, always disconnect the wires connected to the inverter first 
before measuring. Do not make such measurement on the control circuit. 
y The inverter is mainly consisted of semiconductor elements. To prevent the 
negative effects arising from temperature, humidity, dust and vibration etc. in 
working environment and malfunctions caused by components’ aging and 
service life, please perform daily inspection.   
The following table shows the standard replacement interval (years) under 
normal working conditions (average annual ambient temperature = 30°C, load 
factor < 80% and average daily operation period < 12 h).   
 
10.3 Inspection Items 
 
1. Daily inspection: To check if abnormality occurs during operation.   





10. Maintenance and Inspection 
 
123 
A multimeter is normally used to check input and output 
voltage of inverter during operation.   
2. Periodic inspection: To check all locations where inspection can be 
performed only when the inverter is stopped and where 
periodic inspection is required.

10.4 Component Replacement 
 
Wear-out faults are related to endurance period and service life. The 
endurance period largely depends on the working conditions.   
1. For example, service life of relay is determined by roughness of contact 
surface.  
Contact current and load inductance are major factors affecting its service 
life. 
2. The capacitor inside the inverter is used mainly as a smoothing filter. Due to 
the chemical reaction that takes place internally, its service life is greatly 
affected by the temperature. Generally speaking, rising of 10°C in 
temperature reduces the service life of an aluminum electrolytic capacitor by 
half, which also affects the service life of inverter. 
When the inverter is used under high temperature, the aluminum electrolytic 
capacitor may suffer from wear-out faults prior to other components in 
normal status and must be replaced to extend the service life of inverter.

Method of increasing torque at lower speed 
・If higher torque is required at lower speed, the torque boost level can be set 
to a larger value, thus generating higher output voltage to increase the torque. 
 
 
・If the boost level setting is too high, it may cuase overcurrent fault, overload 
fault, motor overheating or excessive noise.   
・The motor current will rise after the boost level increases. Please carefully 
consider the settings for “P016: Electronic Thermal Select” and “P017: 
Thermal Current Setting”. 
・Once it is set to “vector control”, the settings for parameter “P129: Vector 
Control Select =1” and parameter “P007: Torque Boost” will become invalid. 
・During auto torque boost setting, parameter “P130: Motor Capacity”, “P131:

・Overcurrent trip may occur if the value of voltage compensation constant is 
too large. 
・The torque may be insufficient at lower speed if the value of voltage 
compensation contant is too small. 
・The change from manual torqe boost to auto torque boost or vice versa 
cannot be made during operation. 
●Please use the inverter in the following conditions when set to “auto torque 
boost”. 
・The motor must be the squirrel-cage induction type for general purpose. 
・
 
Please select the inverter with capacity equivalent to or one level higher 
than motor capacity.

・Number of motor poles must be “2”, “4” or “6”.   
・It must operate in standalone mode (i.e., one motor is driven by one 
inverter). 
・The maximum wiring length between the inverter and motor must not exceed 
30 m. 
If the above conditions are not satisfied, it is unlikely to achieve sound 
operation performance.

В процессе эксплуатации преобразователя частоты (ПЧ) рано или поздно возникают проблемы, связанные с его корректной работой. Ошибки и сбои могут происходить как при включении (настройке) частотника, так и при его эксплуатации.

При возникновении большинства ошибок преобразователь прекращает работу. Реакцию на некоторые ошибки можно программировать. Например, при возникновении сбоя ПЧ может останавливаться либо продолжать работать, выдав сообщение о неисправности. В некоторых частотных преобразователях существует так называемый «пожарный режим», когда ПЧ работает, несмотря на проблемы, вплоть до поломки и возгорания.

Для начала рассмотрим типичные сообщения об авариях и ошибках ПЧ, которые отображаются на экране пользователя. Отметим, что большинство этих сообщений передаются по каналу связи (если он присутствует) в контроллер и соответствующим образом обрабатываются.

1. Перегрузка по току

Код на дисплее: OC (Over Current). Это сообщение говорит о том, что выходной ток преобразователя частоты превысил допустимое значение. Если данная ошибка появилась при первом пуске ПЧ, необходимо проверить соответствие номинального тока частотника номинальному и реальному току двигателя – возможно, произошло замыкание внутри двигателя. В некоторых типах ПЧ перегрузка OC может разделяться на 3 разных ошибки – перегрузка по току при разгоне, при торможении, при работе на постоянной скорости.

2. Перегрузка

Код на дисплее: OL (Over Load). Данное сообщение связано с предыдущим и в некоторой степени дублирует его. Сообщение OL может высвечиваться из-за срабатывания внутренней электронной тепловой защиты двигателя, либо из-за превышения механической нагрузки на двигатель (превышения момента). Уровень перегрузки устанавливается при настройке частотного преобразователя, причем задаются как уровень тока (в амперах или процентах), так и время реакции в секундах.

3. Превышение напряжения

Код на дисплее: OV (Over Voltage). Это сообщение появляется, когда напряжение на звене постоянного тока превышает допустимый порог. В первую очередь данная ошибка возникает во время торможения, когда электродвигатель входит в режим генерации электроэнергии. Эту проблему можно решить несколькими способами – увеличить время торможения, применить тормозной резистор, отключить торможение (остановка двигателя на свободном выбеге), поднять предельный уровень ограничения перенапряжения при наличии соответствующей возможности.

4. Низкое напряжение

Код на дисплее: LV (Low Voltage). Данное сообщение может появиться, когда напряжение на звене постоянного тока падает ниже установленного порога. Возможные причины: пониженное напряжение в сети, пропадание одной из фаз. К слову, частотный преобразователь может продолжать работать без одной или даже двух фаз, если подключенный двигатель допускает работу на пониженной мощности и отключено обнаружение пропадания фазы.

5. Перегрев ПЧ

Код на дисплее: OH (Over Heat). Это сообщение говорит о том, что температура ПЧ слишком высока. В первую очередь следует проверить исправность внутренних вентиляторов преобразователя и прочистить его сжатым воздухом. Также необходимо проверить отвод тепла от ПЧ, температуру и циркуляцию воздуха внутри электрошкафа. Возможно, потребуется установить дополнительное охлаждение или уменьшить нагрузку.

Мы перечислили лишь основные сообщения о неисправностях. Их число может доходить до нескольких десятков, что позволяет точнее настраивать работу преобразователя и диагностировать неисправности. В различных моделях ПЧ эти сообщения могут индицироваться по-разному, например, в частотнике ProStar PR6000 они выглядят как Er01, Er02, и т.д., но смысл имеют аналогичный.

При ряде неисправностей преобразователей частоты сообщения на экране не выводятся. В основном, это связано с проблемами питания или с фатальными сбоями в работе ПЧ. Кроме того, если существуют проблемы с первоначальным запуском, то есть вероятность ошибки в подключении цепей управления (запуска). Рассмотрим подробнее такие неисправности.

6. Двигатель не запускается

Шаг 1. Проверяем подключение питания и электродвигателя. Шаг 2. Проверяем цепи запуска. В некоторых моделях ПЧ для запуска двигателя необходимо активировать более одного входа, например, «Пуск» и «Вперед», а также вход разрешения работы. Шаг 3. Проверяем способ задания частоты. Проще всего активировать и задать скорость вращения в панели управления, а затем, после устранения проблем, переключиться на задание скорости с внешнего источника.

7. Двигатель вращается в неправильном направлении

Чаще всего в приводах используется «правое» вращение двигателя. Изменить направление вращения можно двумя способами.

• Аппаратный способ. Необходимо поменять любые две фазы питания двигателя на выходе ПЧ.
• Программный способ. Необходимо изменить направление вращения в соответствующем меню («Forward/Reverse»).

8. Двигатель не вращается с нужной скоростью

Причиной может быть неверное задание частоты, либо слишком большая нагрузка на двигатель (при неправильной уставке защиты). Также существует вероятность неверной установки значений верхней и нижней границ выходной частоты.

9. Проблемы с разгоном и торможением

Если двигатель слишком медленно разгоняется, и время разгона существенно превышает установленное, есть вероятность, что срабатывает функция токоограничения при разгоне. Если же двигатель слишком долго тормозит, то необходимо проверить в меню преобразователя настройки такого параметра, как ограничение перенапряжения, и убедиться в правильности подключения тормозного резистора.

10. Слишком большой ток и температура двигателя

Перегрев электродвигателя является следствием чрезмерной нагрузки на его валу. Следует принять меры по защите двигателя и частотного преобразователя путем настройки соответствующих параметров через меню.

В общем случае при возникновении неисправностей в работе преобразователя частоты следует обратить внимание на температуру двигателя и сообщения на экране, а также обратиться к руководству по эксплуатации.

Частотный преобразователь предназначен для плавного изменения скорости и момента, а также он помогает избавиться от пусковых токов. В процессе преобразования постоянного тока в переменный инвертор создает волны переменного тока (синусоидальной, квадратной или любой другой формы). Как всякий стабильный источник питания он должен оставаться способным поставлять достаточно тока для поддержания мощности системы.

Все производители стремятся уменьшить размеры приводов, а потому размещение компонентов и плат в устройстве всё более уплотняется. Это не остаётся бесследным и приводит в какой-то степени к отказам силового оборудования. Необходимо отметить, что ремонт частотников (Р4,0-7,5 кВт) практически нецелесообразен при выходе из строя управляющей части системы. Построение аппарата (свыше 100 кВт) по модульному принципу сильно упрощает функциональную схемуи увеличивает срок службы.

Главный фактор, определяющий срок службы частотника и его бесперебойную эксплуатацию, заключается в своевременных проверках иправильном обслуживании. Кроме всего прочего электронное устройство само по себе является достаточно сложным, поэтому при эксплуатации силового оборудования с ним возникают потенциальные проблемы.

Частотники являются очень чувствительной аппаратурой за счет высокого уровня исполнительских компонентов (если даже не вдаваться в технические детали). Наиболее распространенная проблема преобразовательных устройств — это программное обеспечение. Чем больше добавленных возможностей, тем вполне вероятнее могут возникнуть потенциальные проблемы.

Обычно, починка таких устройств для пользователя обходится довольно дорого. Поэтому некоторые неисправности можно устранить самостоятельно. На самом деле, нет ничего проще, чем взять в руки инструкцию «Коды ошибок преобразователей частоты OMRON» (название взято для примера), и расшифровать сигнализирующие записи с помощью таблицы предупреждений и ошибок. Рассмотрим наиболее распространенные из них.

Неполадки и пути их исправления

Система охлаждения на моделях особенно чувствительна. Можно сказать, это одна из болевых точек механизма. Для того, чтобы максимально увеличить срок эксплуатации частотника следует хотя бы один раз в месяц делать продувание(сжатым воздухом) радиатора охлаждения, расположенного сзади корпуса. Лучше будет, если продуть корпус целиком, ведьвнутри инвертора скапливается всегда очень много пыли.

Продувание радиатора требуется, поскольку на нём крепится IGBT-ключ, через который осуществляется управление электрическим мотором. С выделением тепла радиатор капитально нагревается. Поломка может повлечь за собой перегорание полупроводникового прибора.

Часто на корпусе и радиаторе устанавливаются воздушные вентиляторы с принудительным охлаждением. Периодически их нужно проверять на работоспособность. В случае необходимой замены их несложно найти в продаже. В настоящее время ассортимент этой техники довольно широк и разнообразен.

Частый заряд и разряд, а также повышенная температура со временем приводят к старению электролитических конденсаторов частотника, что уменьшает их номинальную емкость или способствует возникновению внутренних межполюсных пробоев. В результате возможно вздутие или разрушение конденсаторов.

Замена резистора

Регулирование преобразователем частоты может осуществляться как посредством контроллера, так и вручную. Зачастую в неисправное состояние приходит потенциометр (или по-другому резистор). Управлениепроисходит двумя способами:

• с внешнего потенциометра;
• с выносной панельки инвертора.

Для смены неисправного внешнего нужно переключить в настроечном меню частотного преобразователя на опцию регулировки с выносной панельки. Также возможно самому поменять резистор. Параметры резистора и все необходимые операции подробно описываются в инструкции к аппарату.

Сигнализация ошибок

Зачастую возникают предупреждения и ошибки на дисплее устройства при запуске, хотя до остановки их не было. Как правило, после проверки кабелей и протяжек клемм сигнализация об ошибках исчезает. На большинстве моделях это расшифровывается как ошибка при перегрузке. Если один раз в три месяца делать протяжку всех клеммных соединений, такие неприятные ситуации могут вообще не возникать.

Еще одним распространенным слабым местом является то, что при регулировке частотным преобразователем с внешней выносной панельки пропадает управление. Вопреки возникающему ощущению о неисправностивсего аппарата, если просто проверить присоединение кабеля и винтов штекера в разъеме, проблема устраняется.

Электродвигатель не трогается с места

Наиболее серьезная неисправность, требующая замены либо починки частотного преобразователя. При выдаче ошибки о том, что двигатель не трогается с места, могут быть две причины:

• выход из строя электромотора;
• повреждение системы управления. Здесь не обойтись без разборки инвертора и замены электронной платы.

Если самому это сделать сложно, необходимо проконсультироваться с авторизованным сервисным центром для лучшего результата (официального поставщика компании, в нашем случае, OMRON). Иногда бывает проще приобрести новый преобразователь частоты.

При любой неисправности, прежде всего, следует проверить работоспособность электрического мотора, целостность кабельной проводки и клеммных зажимов. А уже после этого разбираться в самом устройстве. А также следует неукоснительно придерживаться правил техники безопасности и всегда помнить про профилактические работына протяжении всей жизнедеятельности аппарата.

Ремонт частотных преобразователей – алгоритм мероприятий

Наладка преобразовательного устройства осуществляется с помощью применения высокочастотных осциллографов. Работу частотника проверяютв трёх возможных режимах, это:

• в номинальном режиме;
• на холостом ходу;
• при максимально допустимой перегрузке.

Невключение тиристоров (транзисторов) частника либо разрыв в силовой цепи определяется по форме выходного напряжения преобразователя. После чего в тиристорном блоке устанавливается выбранный по нужным параметрам тиристор на смену вышедшего из строя.

Ремонт

Наладка системы управления частотником выполняется путём подачи на него питающего напряжения без силового напряжения. Осциллограф позволяет проверить соответствие длительности импульсов, подаваемых на инвертор, указанной в паспорте. В случае искажения сигналов соответствующие элементы системы подвергаются снятию и замене.

Для функционирования современных частотных преобразователей используются интегральные микросхемы. При ремонте и наладке систем помимо осциллографов и тестеров применяется специальная аппаратура.

После капитального ремонта аппарат следует включить в работу на холостом ходу. Затем, если все нормально, запустить инвертор с электродвигателем на холостом ходу, но без его нагрузки. В работе по такому режиму важно проверить отсутствие перегрева элементов привода. Завершающий контроль работы привода проводится при номинальном значении нагрузки двигателя.

После наладки техники иногда требуется прийти к определённому соотношению величин напряжения и частоты. При этом номинал частоты должен соответствовать номиналу напряжения. Для правильной настройки ЭДС следует выполнить такие операции как:

• измерение коэффициента трансформации трансформатора напряжения и активного сопротивления статора электродвигателя;
• расчёт падения напряжения, равного произведению величин активного сопротивления статора на номинальный ток двигателя, разделённому на коэффициент трансформации.
• в итоге, напряжение, снимаемое с отвода резистора, подсоединённого параллельно вторичной обмотке трансформатора, должно быть равным вычисленному значению.

Неисправность в силовой схеме может возникать в результате резких колебаний в системе инвертор—двигатель. Устранение подобных колебаний достигается регулированием резистора блока управления.

Ремонтировать самостоятельно или обратиться в сервис?

Периодическая проверка и техническое обслуживание помогут предотвратить ряд проблем, но, тем не менее преобразователи частоты выходят из строя, и этого нельзя избежать полностью. При серьёзной поломке требуется диагностика техники. Самым ответственным мероприятием считается поиск повреждённых деталей. Ведь случается, приходится искать плавающую неисправность, когда она возникает периодически при определенных условиях или просто хаотично.

В мастерской вам проведут квалифицированную диагностику, включающую в себя главным образом: считывание кодов ошибок, определение вышедших из строя узлов. Будьте готовы заплатить за ремонт.

Ремонт в мастерской – отличное решение, специалисты быстро определят слабые места, и дорогостоящий аппарат еще послужит вам не один год. Ведь бывают случаи, когда пользовательское вмешательство в устройство ухудшало состояние прибора и приводило к окончательной поломке.Если неприятность произошла в период гарантийного обслуживания, то однозначно за помощью лучше обратиться в сервис.
