Number
Cause
Remedy
F07488 Relative positioning not possible
In the mode "direct setpoint input/MDI", for the continuous transfer (p2649
= 1), relative positioning was selected (BI: p2648 = 0 signal). Correct the
selection.
A07489 Reference point offset outside
window
For the function "flying referencing", the difference between the measured
position at the measuring probe and the reference point coordinate is
outside the parameterized window. Remedy:
• Check the mechanical system.
• Check the parameterization of the window (p2602).
F07490 Enable signal withdrawn while
traversing
Set the enable signals.
F07491 STOP cam, minus actuated
Leave the STOP cam minus in the positive traversing direction and retract
the axis to the valid traversing range.
F07492 STOP cam, plus actuated Leave the STOP cam plus in the negative traversing direction and retract
the axis to the valid traversing range.
F07493 Overflow of the value range for the
position actual value
The value range (-2147483648 ... 2147483647) for representing the posi-
tion actual value was exceeded. Remedy:
If necessary reduce the traversing range or position resolution (p2506).
A07495 Reference function interrupted An activated reference function (reference mark search or measuring
probe evaluation) was interrupted. Possible causes:
• Encoder fault
• Reference mark search and measuring probe evaluation simultane-
ously activated (BI: p2508 and BI: p2509 = 1 signal).
• Activated reference function (reference mark search or measuring
probe evaluation) was de-activated (BI: p2508 and BI: p2509 = 0 sig-
nal).
A07496 Enable is not possible It is not possible to enable the basic positioner as at least one signal is
missing. Causes:
• EPOS enable missing (BI: p2656).
• Position actual value, valid feedback signal missing (BI: p2658).
F07499 Reversing cam approached with
the incorrect traversing direction
Check the wiring of the reversing cam (BI: p2613, BI: p2614).
F07503 STOP cam approached with the
incorrect traversing direction
Check the wiring of the STOP cam (BI: p2569, BI: p2570).
A07505 Fixed stop task for U/f/SLVC oper-
ation not possible
Change the open-loop/closed-loop control mode (p1300).
A07557
A07558
Reference point coordinate not in
the permissible range
The received reference point coordinate when adjusting the encoder via
connector input CI: p2599 lies outside half of the encoder range and can-
not be set as actual axis position. Remedy: Correct reference point coor-
dinate.
A07577
A07578
Measuring probe evaluation not
possible
• Set the input terminal for the measuring probe (p0488, p0489 or
p2517, p2518).
• Reduce the frequency of the measuring pulses at the measuring
probe.
A07581
A07582
Position actual value processing
error
Check the encoder for the actual position value processing.
