Faults and alarms
List of faults and alarms
5: Direct setpoint input/MDI and activate traversing task (p2647, p2631).
6: Start referencing and activate traversing task (p2595, p2631).
Remedy: Check the appropriate input signals and correct.
F07458 EPOS: Reference cam not found
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: After starting the search for reference, the axis moved through the maximum permissible distance to search for the
reference cam without actually 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 any reference cam, then set p2607 to 0.
See also: p2606 (EPOS search for reference reference cam maximum distance), p2607 (EPOS search for reference
reference cam present), p2612 (EPOS search for reference reference cam)
F07459 EPOS: No zero mark
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: After leaving the reference cam, the axis has traversed 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 (equivalent zero mark) (p0494).
See also: p0494 (Equivalent zero mark input terminal), p2609 (EPOS search for reference max. distance ref. cam
and zero mark)
F07460 EPOS: End of reference cam not found
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: During the search for reference, when the axis reached the zero mark it also reached the end of the traversing range
without detecting an edge at the binector input "reference cam" (BI: p2612).
Maximum traversing range: -2147483648 [LU] ... -2147483647 [LU]
Remedy: - check the "reference cam" binector input (BI: p2612).
- repeat the search for reference.
See also: p2612 (EPOS search for reference reference cam)
A07461 EPOS: Reference point not set
Reaction: NONE
Acknowledge: NONE
Cause: When starting a traversing block/direct setpoint input, a reference point is not set (r2684.11 = 0).
Remedy: Reference the system (search for reference, flying referencing, set reference point).
A07462 EPOS: Selected traversing block number does not exist
Reaction: NONE
Acknowledge: NONE
Cause: A traversing block selected via binector input p2625 ... p2630 was started via binector input p2631 = 0/1 edge "Acti-
vate traversing task".
- the number of the started traversing block is not contained in p2616[0...n].
- the started traversing block is suppressed.
Alarm value (r2124, interpret decimal):
Number of the selected traversing block that is also not available.
Remedy: - correct the traversing program.
- select an available traversing block number.
