tions
<Abnormal Response>
Field Configuration
• If an error (aside from a communication error) is found in the query content, the Inverter returns
exception responses without performing any operation.
• To determine the cause of an error, check the function code of the response. The function code of
the exception response is the value of the query function code to which 80h is added.
• Check the details of the error with the exception code.
Exception code
<No Response>
The Inverter ignores the query and does not respond if:
• The broadcast is received.
• A communication error is detected in receiving a query.
• The query slave address does not correspond with the slave address set for the Inverter.
• The time interval between 2 pieces of data that configure the message is less than a 3.5-character
length.
• Query data length is inappropriate.
Note: If the timer is set in the master to monitor response, but no response is returned within the set
time period, send the same query again.
