3.6 Exception response:
The brushless DC 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 brushless DC motor drive does not receive the messages due to a communication error;
thus, the brushless DC motor drive has no response. The master device will eventually
process a timeout condition.
The brushless DC 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 brushless DC 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.
Example of an exception response of command code 06H and exception code 02H:
