4 Faults and alarms
4.2 List of faults and alarms
A07486 EPOS: Intermediate stop missing
Message class: Application/technological function faulted (17)
Reaction: NONE
Acknowledge: NONE
Cause: In the modes "traversing blocks" or "direct setpoint input/MDI" at the start of motion, the binector input "no
intermediate stop/intermediate stop" (BI: p2640) did not have a 1 signal.
Remedy: Connect a 1 signal to the binector input "no intermediate stop/intermediate stop" (BI: p2640) and re-start motion.
See also: p2640 (EPOS intermediate stop (0 signal))
A07487 EPOS: Reject traversing task missing
Message class: Application/technological function faulted (17)
Reaction: NONE
Acknowledge: NONE
Cause: In the modes "traversing blocks" or "direct setpoint input/MDI" at the start of motion, the binector input "do not reject
traversing task/reject traversing task" (BI: p2641) does not have a 1 signal.
Remedy: Connect a 1 signal to the binector input "do not reject traversing task/reject traversing task" (BI: p2641) and restart
motion.
See also: p2641 (EPOS reject traversing task (0 signal))
F07488 EPOS: Relative positioning not possible
Message class: Application/technological function faulted (17)
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: In the mode "direct setpoint input/MDI", for continuous transfer (p2649 = 1) relative positioning was selected (BI:
p2648 = 0 signal).
Remedy: Check the control.
A07489 EPOS: Reference point correction outside the window
Message class: Application/technological function faulted (17)
Reaction: NONE
Acknowledge: NONE
Cause: For the function "flying referencing" the difference between the measured position at the measuring probe and the
reference point coordinate lies outside the parameterized window.
Remedy: - check the mechanical system.
- check the parameterization of the window (p2602).
F07490 (N) EPOS: Enable signal withdrawn while traversing
Message class: Application/technological function faulted (17)
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: - for a standard assignment, another fault may have occurred as a result of withdrawing the enable signals.
- the drive is in the "switching-on inhibited" state (for a standard assignment).
Remedy: - set the enable signals or check the cause of the fault that first occurred and then result (for a standard assignment).
- check the assignment to enable the basic positioning function.
F07491 (A) EPOS: STOP cam minus reached
Message class: Application/technological function faulted (17)
Reaction: OFF3
Acknowledge: IMMEDIATELY
Cause: A 0 signal was detected at binector input BI: p2569, i.e. the STOP cam minus was reached.
For a positive traversing direction, the STOP cam minus was reached - i.e. the wiring of the STOP cam is incorrect.
See also: p2569 (EPOS STOP cam minus)
Remedy: - leave the STOP cam minus in the positive traversing direction and return the axis to the valid traversing range.
- check the wiring of the STOP cam.
