Parameters Details
Set the states during deceleration and after stopping, which follow the main power off.
Explanation of Set Values
*1. Decelerating refers to a period between when the motor is running and when the motor speed reaches
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.
*3. Emergency stop refers to immediate stop operation applying control with Servo is still kept ON. At that
time, the torque command value is restricted by the Emergency Stop Torque (Pn511).
Precautions for Correct Use
If an error occurs when the main power supply is turned OFF, the operation conforms to the settings
of Stop Selection for Alarm Detection (Pn510).
If the main power supply is turned OFF in Servo ON state, and if the Undervoltage Alarm Selection
(Pn508) is set to 1, Main power supply undervoltage (AC cut-off detection) (Alarm No.13.1),"occurs.
Follow the Stop Selection for Alarm Detection (Pn510).
