Damage of the devices
A defective motor holding brake or a short circuit on the X21 connection
(motor and built−on accessories) causes internal damage to the device.
Possible consequences:
ƒ If a defective motor holding brake is connected, the replacement device is
also damaged immediately.
Protective measures:
ƒ When devices are replaced due to malfunction of the brake control, ensure
that defect−free motor holding brakes are connected.
ƒ Check whether the motor holding brake and the connecting cable are free
from defects.
ƒ Replace or repair defective components.
