Cause: It is not possible to enable the basic positioner because at least one condition is missing.
Alarm value (r2124, interpr
et decimal):
1: EPOS enable missing.
2: Position actual value, valid feedback signal missing.
Remedy: Check the corresponding missing condition.
A07498 LR: Measuring probe evaluation not possible
Message class: Application/technological function faulted (17)
Message value: %1
Component: None
Response: NONE
Acknowledgment: NONE
Cause: When evaluating the measuring probe, an error occurred.
Alarm v
alue (r2124, interpr
et decimal):
6:
The input terminal for the measuring probe is not set.
4098:
Error when initializing the measuring probe.
4100:
The measuring pulse frequency is too high.
> 50000:
The measuring clock cycle is not a multiple integer of the position controller clock cycle.
Remedy: Deactivate measuring probe evaluation (c2509 = 0 signal).
For alarm value = 6:
Se
t the input terminal for the measuring probe (p0488, p0489 or p2517, p2518).
For alarm value = 4098:
Check the Control Unit hardware.
For alarm value = 4100:
Reduce the frequency of the measuring pulses at the measuring probe.
For alarm value > 50000:
Set the clock cycle ratio of the measuring clock cycle to the position controller clock cycle to an integer multiple.
To do this, the currently e󹪜ective measuring clock cycle can be determined from the alarm value as follows:
Tmeas [125 µs] = alarm value - 50000
With PROFIBUS, the measuring clock cycle corresponds to the bus clock cycle (r2064[1]).
Without PROFIBUS, the measuring clock cycle is an internal cycle time that cannot be in󹪞uenced.
F07499 EPOS: Reversing cam approached with the incorrect traversing direction
Message class: Application/technological function faulted (17)
Message value: -
Component: None
Response: OFF3
Acknowledgment: IMMEDIATELY
Cause: The negative reversing cam was approached in the positive traversing direction, or the positive reversing cam was
appr
oached in t
he negative traversing direction.
See also: c2613 (EPOS active homing negative reversing cam), c2614 (EPOS active homing positive reversing cam)
Remedy: - Check the wiring of the reversing cam (c2613, c2614).
- Check the tr
aversing direction to approach the reversing cam.
F07503 EPOS: Hardware limit switch approached with the incorrect traversing direction
Message class: Application/technological function faulted (17)
