The drive controller is interrupted if:
§ A29 = 0: Inactive for STOBER device controller
or
§ A540 = 0: disable drive, motor is free to rotate for CiA device controller
Response:
§ The power unit is disabled and axis movement is no longer controlled by the drive controller

inactive release override (F06)
The drive controller is interrupted with a quick stop if:
§ A29 = 1: Active for STOBER device controller
or
§ A540 = 2: slow down on quick stop ramp for CiA device controller
Response:
§ The axis is stopped by a quick stop; meanwhile, the brakes are controlled by the drive
controller and remain released
§ At the end of the quick stop, the power unit is disabled and axis movement is no longer
controlled by the drive controller; the brakes are no longer controlled by the drive controller
and engage in the event of an inactive release override (F06)
