 0: Decelerate to stop
After the stop command is enabled, the AC drive decreases the output frequency
according to the deceleration time and stops when the frequency decreases to zero.
 1: Coast to stop
After the stop command is enabled, the AC drive immediately stops the output. The
motor will coast to stop based on the mechanical inertia.
