P 5.12.2.1 Brake Output
0 Indicates that the mechanical brake is disabled. Use the value 10105 to set a digital output where 1 refers to the control board, 01
refers to the option, and 05 refers to the terminal number.
Additional selections appear based on the hardware of the options connected to the drive and the available fieldbuses.
P 5.12.2.2 Brake Priming Torque
Set the torque to be build up against the mechanical brake during priming before releasing the brake.
Default Value:
100
Parameter 3012
Number:
Data Type: REAL
P 5.12.2.2 Brake Priming Torque
The value is set as percent of nominal torque. The value defines the torque applied against the closed mechanical brake before release.
The torque/load on a crane is positive and is 10– 160%. To obtain the best starting point, set the parameter to approximately 70%.
The torque/load on a lift can be both positive and negative and between -160% and +160%. To obtain the best starting point, set the
parameter to 0%. The higher the torque error, the more movement during load takeover.
P 5.12.2.3 Brake Priming Direction
Select the direction of the applied torque during priming before releasing the brake.
Default Value: 0 (Clockwise)
