Event 53: Limit switch
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
§
The brakes are no longer controlled by the drive controller and engage in the event of an 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)
