4 Faults and alarms
4.2 List of faults and alarms
4: Direct setpoint input/MDI and starting referencing (p2647, p2595).
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
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None
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.
F07459 EPOS: No zero mark
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None
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) (p0495).

F07460 EPOS: End of reference cam not found
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None
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.
A07461 EPOS: Reference point not set
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None
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).
