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.
