13.3.33 Event 78: Position limit cyclic
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)
Number Cause Check and action
1: Illegal direction Reference position outside of
the software limit switch
Check the reference position in the
controller and software limit switch in the
drive controller and correct it if
necessary (STOBER I50, I51 or CiA 402
A570)
2: Reference value outside of
circular length I01
Reference position outside of
the travel range
Check the reference position in the
controller and travel range in the drive
controller and correct it if necessary
(STOBER I01 or CiA 402 A568)
3: Maximum extrapolation
time I423 exceeded
Missing update of the
reference position
Check the task cycle time in the fieldbus
master of the controller and maximum
permitted extrapolation in the drive
controller and correct it if necessary
(I423)
