Remedy: De-activate the measuring probe evaluation (BI: p2509 = 0 signal).
Re alarm value = 6:
Set the input terminal for the measuring probe (p0488, p0489 or p2517, p2518).
Re alarm value = 4098:
Check the Control Unit hardware.
Re alarm value = 4100:
Reduce the frequency of the measuring pulses at the measuring probe.
Re 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 effective 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 PROFIBUS clock cycle (r2064[1]).
Without PROFIBUS, the measuring clock cycle is an internal cycle time that cannot be influenced.
F07499 (A) EPOS: Reversing cam approached with the incorrect traversing direction
Reaction: OFF3
Acknowledge: IMMEDIATELY
Cause: The reversing cam MINUS was approached in the positive traversing direction or the reversing cam PLUS was
approached in the negative traversing direction.
See also: p2613 (EPOS search for reference reversing cam minus), p2614 (EPOS search for reference reversing
cam plus)
Remedy: - check the wiring of the reversing cam (BI: p2613, BI: p2614).
- check the traversing direction to approach the reversing cam.
F07503 EPOS: STOP cam approached with the incorrect traversing direction
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The STOP cam MINUS was approached in the positive traversing direction or the STOP cam PLUS was approached
in the negative traversing direction.
Remedy: - check the wiring of the STOP cam (BI: p2569, BI: p2570).
- check the traversing direction to approach the STOP cam.
A07505 EPOS: Task fixed stop not possible in the U/f/SLVC mode
Reaction: NONE
Acknowledge: NONE
Cause: In the U/f/SLVC mode, an attempt was made to execute a traversing block with the "fixed stop" task. This is not pos-
sible.
Alarm value (r2124, interpret decimal):
Number of the traversing block with an illegal task parameter.
Remedy: - Check the traversing block and change the task.
- change the open-loop/closed-loop control mode (p1300).
See also: p1300 (Open-loop/closed-loop control operating mode), p2621 (EPOS traversing block task)
A07530 Drive: Drive Data Set DDS not present
Reaction: NONE
Acknowledge: NONE
Cause: The selected drive data set is not available (p0837 > p0180). The drive data set was not changed over.
See also: p0180 (Number of Drive Data Sets (DDS)), p0820 (Drive Data Set selection DDS bit 0), p0821 (Drive Data
Set selection DDS bit 1), r0837 (Drive Data Set DDS selected)
Remedy: - select the existing drive data set.
- set up additional drive data sets.
A07531 Drive: Command Data Set CDS not present
Reaction: NONE
Acknowledge: NONE
Cause: The selected command data set is not available (p0836 > p0170). The command data set was not changed over.
See also: p0810 (Command data set selection CDS bit 0), p0811 (Command data set selection CDS bit 1), r0836
(Command Data Set CDS selected)
