  1. To prevent electric shock, note the following: WARNING Before wiring or inspection, turn off the power and wait for 15 minutes or more (20 minutes or for drive unit 30kW or more) until the charge lamp turns off. Then, confirm that the voltage between P( ) and N( ) (L and L for drive unit 30kW or more) is safe with a voltage tester and others.

  4. Additional instructions The following instructions should also be fully noted. Incorrect handling may cause a fault, injury, electric shock, etc. (1) Transportation and installation CAUTION Transport the products correctly according to their weights. Stacking in excess of the specified number of products is not allowed. Do not carry the servo motor by the cables, shaft or encoder.
• Page 5
  Never hit the servo motor or shaft, especially when coupling the servo motor to the machine. The encoder may become faulty. Do not subject the servo motor shaft to more than the permissible load. Otherwise, the shaft may break. When the equipment has been stored for an extended period of time, consult Mitsubishi. (2) Wiring CAUTION Wire the equipment correctly and securely.

  COMPLIANCE WITH EC DIRECTIVES 1. WHAT ARE EC DIRECTIVES? The EC directives were issued to standardize the regulations of the EU countries and ensure smooth distribution of safety-guaranteed products. In the EU countries, the machinery directive (effective in January, 1995), EMC directive (effective in January, 1996) and low voltage directive (effective in January, 1997) of the EC directives require that products to be sold should meet their fundamental safety requirements and carry the CE marks (CE marking).

  7. SPECIAL ADJUSTMENT FUNCTIONS 7. SPECIAL ADJUSTMENT FUNCTIONS POINT The functions given in this chapter need not be used generally. Use them if you are not satisfied with the machine status after making adjustment in the methods in chapter 7. If a mechanical system has a natural resonance point, increasing the servo system response level may cause the mechanical system to produce resonance (vibration or unusual noise) at that resonance frequency.

Has vibration or unusual noise occurred? Execute or re-execute adaptive tuning. (Set parameter No. PB01 to «0001».) Tuning ends automatically after the If assumption fails after tuning is executed at predetermined period of time.

  7. SPECIAL ADJUSTMENT FUNCTIONS POINT «Filter OFF» enables a return to the factory-set initial value. When adaptive tuning is executed, vibration sound increases as an excitation signal is forcibly applied for several seconds. When adaptive tuning is executed, machine resonance is detected for a maximum of 10 seconds and a filter is generated.

  7. SPECIAL ADJUSTMENT FUNCTIONS POINT When machine end vibration does not show up in motor end vibration, the setting of the motor end vibration frequency does not produce an effect. When the anti-resonance frequency and resonance frequency can be confirmed using the machine analyzer or external FFT device, do not set the same value but set different values to improve the vibration suppression performance.
