Remedy
In the mode "direct setpoint input/MDI", for the continuous transfer (p2649
= 1), relative positioning was selected (BI: p2648 = 0 signal). Correct the
selection.
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).
•
Set the enable signals.
Leave the STOP cam minus in the positive traversing direction and retract
the axis to the valid traversing range.
Leave the STOP cam plus in the negative traversing direction and retract
the axis to the valid traversing range.
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).
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).
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).
•
Check the wiring of the reversing cam (BI: p2613, BI: p2614).
Check the wiring of the STOP cam (BI: p2569, BI: p2570).
Change the open-loop/closed-loop control mode (p1300).
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.
Set the input terminal for the measuring probe (p0488, p0489 or
•
p2517, p2518).
Reduce the frequency of the measuring pulses at the measuring
•
probe.
Check the encoder for the actual position value processing.
