NOTICE
Destruction of the converter as the armature short-circuit contactor incorrectly switches
Incorrect switching of the armature short-circuiting contactor can erode the contactor
contacts and destroy the converter.
• Program the converter so that pulses are first canceled and this is actually implemented
In servo motors with an integrated holding brake, you can produce additional braking torque
with the holding brake.
Note
The holding brake is not a working brake to brake a spinning motor. A limited number of
EMERGENCY STOP operations is permissible.
Additional information is provided in Chapter "Holding brake (Page 44)".
Note
Braking under normal operating conditions must always be performed via the setpoint input.
For further information, see the configuration manual of the converter.
