Encoder Mode
The parameter Encoder Mode offers the possibility to select which values should be calculated from the encoder position:
‘POS’: The actual position is determined.‘POSVELO’: The actual position and the actual velocity are determined.‘POSVELOACC’: The actual position, the actual velocity and the actual acceleration are determined.
Position Correction
The Position Correction can be activated under MOTION | NC-Task 1 SAF | Axes | Axis 1 | Parameter.
Alternatively, the Position Correction can be activated under MOTION | NC-Task 1 SAF | Axes | Axis 1 | Enc | Parameter.
Similar for other identifiers.
FALSE: The Position Correction is disabled.
TRUE: The Position Correction is enabled.
The variable axis.PlcToNc.PositionCorrection is of data type LREAL and belongs to the structure PLCTONC_AXIS_REF. If Position Correction is enabled, this variable adds an additional offset to the target position. It should be noted that this correction does not affect the software end positions.
Filter Time Position Correction (P-T1)
The filter time for the PT-1 filter, which filters fluctuations within the Actual Position Correction with the filter time set here. See section PT1 Filter for further information on the PT1 filter.

MC_PositionCorrectionLimiter
The function block MC_PositionCorrectionLimiter adds the correction value PositionCorrectionValue to the actual position value of the axis. Depending on the CorrectionMode the position correction value is either written directly or filtered.
