Abstract:
PROBLEM TO BE SOLVED: To provide a servomotor stop control device which cuts off power supply to a servo amplifier at an emergency stop to enable the servomotor to stop safely and securely.SOLUTION: The servomotor stop control device is configured to output a stop operation instruction to stop a servo motor 11a to a servo amplifier 50, when an operation command output unit 23 detects an emergency stop signal. Further, when a regeneration state detection unit 22 detects that the servo amplifier 50 is in a regeneration state during the process of stop control based on the stop operation command, a feeder circuit control unit 21 controls a servo feeder circuit 60 to cut off power supply to the servo amplifier 50.SELECTED DRAWING: Figure 1
