Holding Brake Functionality

The brake function must be enabled through a drive parameter.

• The following image shows the timing and functional relationships between the controlled stop signal, speed, and braking force.
  • All values can be adjusted with drive parameters; values in the diagram are default values.
• The parameters shown are specific to Kollmorgen AKD2G drives and Kollmorgen Essentials Drive.
  • See WorkBench Help - AKD2G for the drive parameter details.
• The drive speed setpoint is internally driven down an adjustable ramp (AXIS#.CS.DEC) to 0 V.
• With default values, the output for the brake is switched on when the speed has reached 5 rpm (AXIS#.ZEROV) for at least 6 ms (AXIS#.ZEROT).
• The rise (t_BRH[ms]) and fall (t_BRL[ms]) times of the holding brake built into the servo motor are different for the various types of servo motor.
