Remedy
Correct the traversing block.
•
Change the software limit switch minus (CI: p2578, p2580).
•
Change the software limit switch plus (CI: p2579, p2581).
•
Correct the target position in the traversing block.
•
Change the modulo range (p2576).
•
Correct the traversing block.
Move away in the positive direction.
Move away in the negative direction.
Correct the target position.
Correct the target position.
•
Change the software limit switch minus (CI: p2578, p2580).
•
Change the software limit switch plus (CI: p2579, p2581).
•
Correct the target position.
•
Change the software limit switch minus (CI: p2578, p2580).
•
Change the software limit switch plus (CI: p2579, p2581).
•
Correct the target position.
•
Change the software limit switch minus (CI: p2578, p2580).
•
Change the software limit switch plus (CI: p2579, p2581).
•
Check the maximum torque-generating current (r1533).
•
Check the torque limits (p1520, p1521).
•
Check the power limits (p1530, p1531).
•
In the "Fixed stop reached" state, the axis has moved outside the defined
monitoring window (p2635). Remedy:
Check the monitoring window (p2635).
•
Check the mechanical system.
•
In a traversing block with the FIXED STOP task the end position was
reached without detecting a fixed stop. Remedy:
Check the traversing block and locate the target position further into
•
the workpiece.
Check the "fixed stop reached" control signal (p2637).
•
Reduce the maximum following error window to detect the fixed stop
•
(p2634).
Connect a "1" signal at the binector input "no intermediate
stop/intermediate stop" (BI: p2640) and re-start motion.
Connect a "1" signal at the binector input "do not reject traversing
task/reject traversing task" (BI: p2641) and re-start motion.
