Cause
The target position for relative traversing
lies outside the traversing range.
The target position for relative traversing
lies outside the traversing range.
The actual position of the axis is less than
the position of the software limit switch
minus.
The actual position of the axis is greater
than the position of the software limit
switch plus.
For a standard assignment, another
•
fault may have occurred as a result of
withdrawing the enable signals.
The drive is in the "switching on inhibit-
•
ed" state (for a standard assignment).
The STOP cam minus was reached. For a
positive traversing direction, the STOP
cam minus was reached, i.e. the wiring of
the STOP cam is incorrect.
The STOP cam plus was reached. For a
negative traversing direction, the STOP
cam plus was reached, i.e. the wiring of
the STOP cam is incorrect.

Remedy
Correct the target position.
Correct the target position.
Correct the target position.
•
Change software limit switch minus (CI:
•
p2580).
Correct the target position.
•
Change software limit switch plus (CI:
•
p2581).
Set the enable signals or check the cause
•
of the fault that first occurred and then re-
sult (for a standard assignment).
Check the assignment to enable the basic
•
positioning function.
Leave the STOP cam minus in the posi-
•
tive traversing direction and return the ax-
is to the valid traversing range.
Check the wiring of the STOP cam.
•
Leave the STOP cam plus in the negative
•
traversing direction and return the axis to
the valid traversing range.
Check the wiring of the STOP cam.
