Description
By default, when the Hardware Disable input deactivates, the drive is immediately disabled. However, on a vertical axis this may allow the load to drop slightly before the brake is applied.
To ensure that the brake is applied before the power stage is disabled, set DRV.HWENDELAY to a value which allows the brake to apply fully.
While the brake is applying, the drive will also attempt to decelerate the motor using the standard drive disable settings such as DRV.DISMODE, CS.DEC, CS.VTHRESH and CS.TO.

Prior to version 01-05-08-000, the brake would only apply when velocity dropped below CS.VTHRESH or MOTOR.TBRAKETO expired.
Starting with 01-05-08-000, the brake will now apply immediately when the Hardware Enable Input line is deactivated.
