Example: Task description, assumptions:
Motor with motor
A motor with holding brake for a hanging axis is connected to drive A.
holding brake
The motor holding brake is to be controlled via output terminal O3.A.
What other settings are required?
1. Connect–up the relay to control the motor holding brake
2. Assign the function "holding brake" to output terminal O3.A (P0683
3. Activate the brake sequence control in the drive (P0850 = 1)
4. Set the parameter to open the holding brake
5. Set the parameters for closing the holding brake when withdrawing

= 35)
P0851 (brake opening time)
This time must be set, so that it is equal to or greater than the time
to open the holding brake.
the controller enable
P0852 (speed, close holding brake)
P0853 (brake delay time)
The brake delay time (P0853) must be harmonized with the speed
at which the holding brake closes (P0852).
P0854 (controller inhibit time)
The controller inhibit time must be harmonized with the time that it
takes to close the brake so that the drive cannot drop.
Example of determining the controller inhibit time:
Mark the position of the axis and initiate an alarm that withdraws the
controller enable.
Does the axis sag? If yes, then increase the controller inhibit time
