A07457 Combination of input signals is not
permissible
An illegal combination of input signals, which are simultaneously set was
detected, e.g.:
• Jog 1 and jog 2 (p2589, p2590).
• Jog 1 or jog 2 and direct setpoint input/MDI (p2589, p2590, p2647).
• Jog 1 or jog 2 and start referencing (p2589, p2590, p2595).
• Jog 1 or jog 2 and activate traversing task (p2589, p2590, p2631).
• Direct setpoint input/MDI and start referencing (p2647, p2595).
• Direct setpoint input/MDI and activate traversing task (p2647, p2631).
• Start referencing and activate traversing task (p2595, p2631).
F07458 Reference cam not found After starting the reference point approach, the axis has traversed
through the maximum permissible distance to search for the reference
cam without finding the reference cam. Remedy:
• Check the "reference cam" binector input (BI: p2612).
• Check the maximum permissible distance to the reference cam
(p2606).
• If axis does not have a reference cam, then set p2607 to 0.
F07459 No zero mark available After leaving the reference cam, the axis traversed through the maximum
permissible distance between the reference cam and zero mark without
finding the zero mark. Remedy:
• Check the encoder regarding the zero mark.
• Check the maximum permissible distance between the reference cam
and zero mark (p2609).
• Use an external encoder zero mark (p0494).
F07460 End of reference cam not found During the reference point approach, the axis, when approaching the zero
mark, has reached the end of the traversing range without identifying an
edge at the binector input "Reference cam" (BI: p2612). Remedy:
• Check the "reference cam" binector input (BI: p2612).
A07461
Reference point not set
Reference the system
A07462 Selected traversing block number
does not exist
Correct the traversing program.
A07463 External block change not request-
ed in the traversing block
Resolve the reason why the edge is missing at binector input (BI: p2632).
F07464 Traversing block is inconsistent Check the traversing block and, if necessary, take into consideration any
alarms that are present.
A07465 Traversing block does not have a
subsequent block
• Parameterize this traversing block with the step enabling condition
END.
• Parameterize additional traversing blocks with a higher block number
and for the last block, parameterize the step enabling condition END.
A07466 Traversing block number assigned
a multiple number of times
Correct the traversing blocks.
A07467 Traversing block has illegal task
parameters
Correct the task parameter in the traversing block.
A07468 Traversing block jump target does
not exist
• Correct the traversing block.
• Add the missing traversing block.
