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.
In the "fixed stop reached" state, the axis
has moved outside the defined monitoring
window (p2635).
Remedy
Correct the target position.
Correct the target position.
Correct the target position.
•
Change software limit switch minus (CI:
•
p2580).
See also: p2580 (EPOS software limit switch
minus), p2582 (EPOS software limit switch
activation)
Correct the target position.
•
Change software limit switch plus (CI:
•
p2581).
See also: p2580 (EPOS software limit switch
minus), p2582 (EPOS software limit switch
activation)
Check the monitoring window (p2635).
•
Check the mechanical system.
