Note: 2116H is the number display for Pr.00.04. The high byte of 2117H is the number of decimal places
for 2116H. The low byte of 2117H is the ASCII code of the alphabetic display for Pr.00.04.
6. Exception response:
The AC motor drive is expected to return a normal response after receiving command messages from the
master device. The following describes the conditions when no normal response is returned to the master
device.
The AC motor drive does not receive the messages due to a communication error, and the AC motor drive
has no response. The master device eventually processes a time-out condition.
The AC motor drive receives the messages without a communication error, but cannot handle them. An
exception response is returned to the master device and a fault message “CExx” displays on the AC motor
drive keypad. The xx of “CExx” is a decimal code equal to the exception code (described below).
In the exception response, the most significant bit of the original command code is set to 1, and an
exception code that explains the condition that caused the exception is returned.
The following is an example of an exception response of command code 06H and exception code 02H.
