Number
Cause
Remedy
A07469 Traversing block target position <
software limit switch minus
• Correct the traversing block.
• Change the software limit switch minus (CI: p2578, p2580).
• Change the software limit switch plus (CI: p2579, p2581).
A07470 Traversing block target position >
software limit switch plus
A07471 Traversing block target position
outside the modulo range
• Correct the target position in the traversing block.
• Change the modulo range (p2576).
A07472 Traversing block
ABS_POS/ABS_NEG not possible
Correct the traversing block.
A07473 Beginning of traversing range
reached
Move away in the positive direction.
A07474
End of traversing range reached
Move away in the negative direction.
F07475 Target position < start of traversing
range
Correct the target position.
F07476 Target position > end of traversing
range
A07477 Target position < software limit
switch minus
• Correct the target position.
• Change the software limit switch minus (CI: p2578, p2580).
• Change the software limit switch plus (CI: p2579, p2581).
A07478 Target position > software limit
switch plus
A07479 Software limit switch, minus actu-
ated
• Correct the target position.
• Change the software limit switch minus (CI: p2578, p2580).
• Change the software limit switch plus (CI: p2579, p2581).
A07480 Software limit switch, plus actuated
F07481
Axis position < software limit switch
minus
• Correct the target position.
• Change the software limit switch minus (CI: p2578, p2580).
• Change the software limit switch plus (CI: p2579, p2581).
F07482
Axis position > software limit switch
plus
A07483 Travel to fixed stop, clamping
torque not reached
• Check the maximum torque-generating current (r1533).
• Check the torque limits (p1520, p1521).
• Check the power limits (p1530, p1531).
F07484 Fixed stop outside the monitoring
window
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.
F07485 Fixed stop is not reached 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).
A07486 Intermediate stop missing Connect a "1" signal at the binector input "no intermediate
stop/intermediate stop" (BI: p2640) and re-start motion.
A07487 Reject traversing task missing Connect a "1" signal at the binector input "do not reject traversing
task/reject traversing task" (BI: p2641) and re-start motion.
