Connecting
4.7 Motor holding brake
The holding brake is built in the servo motors with brakes.
For 400 V variant servo drive, a motor holding brake interface (X7) is integrated in the front
panel. You can connect it to a servo motor with brake to use the function of motor holding
brake directly.
For 200 V variant servo drive, no specific interface is integrated. To use the function, you
need to connect the drive to a third-party device via the control/status interface (X8).
Note
• Use this brake for the "hold" purpose only, that is, to hold the stalling state only. Never
use this for the "brake" purpose to stop the load in motion. Use the holding brake only to
hold a stopped motor.
• The holding brake is activated at the same time when the motor power is cut off.
