11.12.5.3 Process when brake is closed

The following process occurs if the enable of the requested basic function for traversing the drive is

deactivated again:

1. The drive is brought to standstill via the basic function "Stop

", or, where required, also via the

basic function "Quick stop

".

2. When speed setpoint and actual speed value have fallen below the speed threshold set in

C02581

:

• The output BRK_bReleaseBrakeOut is set to FALSE for closing the brake.

• The current torque is saved, so that, if necessary, it can be used for feedforward control

during the next start.

• Monitoring of the motor brake control module is deactivated temporarily.

• Monitoring of the status input is deactivated temporarily (if switched active via C02583

).

• The elapse of the brake application time starts.

3. After the brake closing time has elapsed and the corresponding state change of the status

signal:

• The output BRK_bBrakeReleased is reset to FALSE.

• The controller inhibit is activated.

4. After the additional waiting time set for the status monitoring in C02591

has elapsed:

• Monitoring of the motor brake control module is active again.

• Monitoring of the status input is active again (if switched active via C02583

).

• Standstill monitoring is activated.Standstill monitoring
