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).
In a traversing block with the task FIXED
STOP, the end position was reached with-
out detecting a fixed stop.
In the mode "direct setpoint input/MDI", for
continuous transfer relative positioning
was selected.
11.2 List of faults and alarms
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).
Check the monitoring window (p2635).
•
Check the mechanical system.
•
Check the traversing block and locate the
•
target position further into the workpiece.
Check the "fixed stop reached" control
•
signal.
If required, reduce the maximum following
•
error window to detect the fixed stop
(p2634).
Check the control.
