Exception Responses:
Except for broadcast messages, the AC drive is been expected to return a normal response
after receiving command messages from the master device. The following depicts the
conditions that no normal response is replied to the master device.
The AC drive does not receive the messages due to a communication error; thus, the AC
drive has no response. The master device will eventually process a timeout condition.
The AC drive receives the messages without a communication error, but cannot handle it,
an exception response will return to the master device. In the exception response, the most
significant bit of the original command code is set to 1, and an exception code explains the
condition that caused the exception is returned. An example of exception response of
command code 06H and exception code 02H:
