MOTOR.BRAKERLS

Description

This command allows a user to release or apply the motor brake.

0 = Drive controls the brake.

1 = Brake is released.

2 = Brake is applied.


  • If a vertical axis is stationary and disabled, toggling the brake with MOTOR.BRAKERLS will not reapply the brake until controlled stop conditions are met (the axis actual velocity has been less than CS.VTHRESH for CS.TO milliseconds). In order for the brake to reapply immediately when commanding MOTOR.BRAKERLS, set CS.VTHRESH to a value greater than the velocity possible by the free falling axis and set CS.TO to 1 millisecond (its minimum value) prior to making the command.

  • A digital input mode can also be used for the same purpose. The two mechanisms are independent.
