Cause
The task parameter in the traversing block
contains an illegal value.
Alarm value (r2124, interpret decimal):
Number of the traversing block with an
illegal task parameter.
In a traversing block, a jump was pro-
grammed to a non-existent block.
Alarm value (r2124, interpret decimal):
Number of the traversing block with a jump
destination that does not exist.
In the traversing block the specified abso-
lute target position lies outside the range
limited by the software limit switch minus.
In the traversing block the specified abso-
lute target position lies outside the range
limited by the software limit switch plus.
In the traversing block the target position
lies outside the modulo range.
In the traversing block the positioning
mode ABS_POS or ABS_NEG were pa-
rameterized with the modulo correction not
activated.
When traversing, the axis has moved to
the traversing range limit.
When traversing, the axis has moved to
the traversing range limit.
Remedy
Correct the task parameter in the traversing
block.
Correct the traversing block.
•
Add the missing traversing block.
•
Correct the traversing block.
•
Change software limit switch minus
•
(p2580).
Correct the traversing block.
•
Change software limit switch plus (p2581).
•
In the traversing block, correct the target
•
position.
Change the modulo range (p29246).
•
Correct the traversing block.
Move away in the positive direction.
Move away in the negative direction.
