PLC Offset.

PLCOINC
PLC offset increment per cycle.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values (1): From 0 to 99999.9999 mm/min.
Possible values (2): From 0 to 3937.00787 inch/min.
Possible values (3): From 0 to 99999.9999 degrees/min.
Default value: 0 (they are assumed instantaneously).
Associated variable: (V.)[ch].MPA.PLCOINC.xn
The PLC offset is an additional compensation over the real coordinate of the axis. The CNC
applies this compensation in a transparent way for the user who will not see it reflected in
the coordinates. A typical utility is to correct the axis dilatations due to temperature.
This parameter indicates whether the CNC assumes the PLC offsets instantaneously in a
sampling period (cycle time) or in steps.
Example:
It is set PLCOINC = 0.001 mm (one micron per CNC cycle). If the PLC Offset had an initial
value of 0.25 mm and the new value is 0.30 mm, the PLC offset applied per cycle will be:
0.250 0.251 0.252 0.253 · · · 0.297 0.298 0.299 0.300
The PLC offset to be applied is set in the variable (V.)A.PLCOF.xn. The PLC offset applied
so far may be checked in the variable (V.)A.ACTPLCOF.xn.
