3.3.2.1 Function
The device has 1 switching output for direct connection of the holding brake in the motor.
Output Connection Name in the CMMT plug-in Description
BR+/BR- X6 Holding brake 1 Motor holding brake
Tab. 113 Output for the brakes (holding brake)
The output is intended for the actuation of a brake that drops when the system is in a non-energised
status and holds the motor and/or axis in position.
The mechanical delay of the brake means that release and activation takes a certain length of time.
The behaviour of the device can be adapted to the mechanical delay of the brake using parameters:
Parameters Description
Switch-on
delay Delay in switching on the closed-loop controller until a command is accepted
–
The holding brake is not released until the controller is enabled. The closed-
loop controller takes over the control (actual position = setpoint position).
– No orders are accepted until the switch-on delay has elapsed, so the holding
brake can release completely.
– After the switch-on delay has elapsed, orders are accepted.
