30 r/min or less. Once the motor reaches a speed of 30 r/min or less and moves to the after stop
status, follow the subsequent operation based on the after stop status regardless of the motor speed.
*2. The motor may make a sudden motion.

emergency
stop at an error. An
emergency
stop takes place by the Operation A, when an
emergency
