9-4-8 Communication Errors

Exception Response
When the inverter receives a message that does not contain communication errors but the message can not
be processed, the inverter will return an exception response. The exception response contains an error
sub-code in the data field that represents the problem.

Exception Response Errors

Sub-Code Name

Causes

1

Illegal Function

Received RTU Function other than 03, 06 or 16

2

Illegal Data Address

• The starting parameter address is an unused inverter parameter.
• The starting parameter address plus the offset refers to inverter

parameter greater than the last parameter in a Function Code sort.

• The number of registers is greater than 16.

3

Illegal Data Value

Data contains an out of range value for an inverter parameter

7

Negative Acknowledge

• Requested data cannot be changed while the inverter is running.
• The inverter parameter function is owned by the network interface

option card and cannot be changed.

Communication errors
Communication errors occur when the inverter receives an invalid message. The inverter will not return a
response to a communication error. A code that represents the last communication error is stored in
inverter parameter M26. Typical communication message errors include parity, framing, and CRC errors.
