Warnings and troubleshooting
W01 W01SWLL Left SW limit
Motor has reached maximum left
position and must not exceed this.
Rectification of problem:
Adapt the “Lower SW limit” value under the “Protection” tab in the “Ap-
plication center”.
W02 W02SWRL Right SW limit
Motor has reached maximum right
position and must not exceed this.
Rectification of problem:
Adapt the “Upper SW limit” value under the “Protection” tab in the “Ap-
plication center”.
W03 W03HWLL Left HW limit
Negative hardware limit switch active.
Motor must not exceed this position.
Rectification of problem:
Check whether the hardware limit switch has actually triggered. Also
check in the “I/O set/test” window whether the limit switch logic is set
correctly.
