3.6 Exception response:

The AC motor drive is expected to return a normal response after receiving command

messages from the master device. The following depicts the conditions when no

normal response is replied to the master device.

The AC motor drive does not receive the messages due to a communication error; thus, the AC

motor drive has no response. The master device will eventually process a timeout

condition.

The AC motor drive receives the messages without a communication error, but cannot handle

them. An exception response will be returned to the master device and an error

message “CExx” will be displayed on the keypad of AC motor drive. The xx of “CExx”

is a decimal code equal to the exception code that is described below.

In the exception response, the most significant bit of the original command code is set to 1, and

an exception code which explains the condition that caused the exception is

returned.
