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.

Error Propagation Mode
For the slave axis the error transmission can be delayed.
‘INSTANTANEOUS’
: The error transmission is not delayed.
‘DELAYED’
: The error transmission is delayed by the Error Propagation Delay.
Error Propagation Delay
The delay time by which error propagation for the slave axis is delayed when Error Propagation Mode ‘DELAYED’
is selected.
If an error occurs at a slave axis during runtime, the corresponding master axis is not set to error state until the time assigned here has elapsed. A state of interest of the slave axis, especially its error state, can be observed by PLC code. In this way, the faulty slave axis can be safely decoupled to safely prevent the entire axis combination from entering the error state.
Couple slave to actual values if not enabled
FALSE
: Not coupled.
TRUE
: Coupled. The slave axis follows the master actual position while and also when the master is disabled.
Velocity Window und Filter Time for Velocity Window
The coupled slave axis follows the master axis within the Velocity Window
. If velocity deviations exceed Filter Time for Velocity Window
beyond Velocity Window
, an error is output.
Allow motion commands
Allow motion commands to slave axis
In general terms, an axis is in PTP mode all the time. This is about indirectly converting a slave axis into a master axis. Thus it is implicitly decoupled without the need to call on MC_GearOut
from the PLC code.
TRUE
: A PTP command can be triggered to the slave axis without first setting the axis to PTP mode.
FALSE
: Before a PTP command can be triggered to the slave axis, the slave axis must be set to PTP mode.
Allow motion commands to external setpoint axis
FALSE
: Before a PTP command can be triggered to the external setpoint axis, the external setpoint axis must be set to PTP mode.
TRUE
: A PTP command can be triggered to the external setpoint axis without first setting the axis to PTP mode.
Dead Time Compensation (Delay Velo and Position)
This parameter is only present for compatibility reasons. Do not use it on new projects.
Data Persistence
Data Persistence is used for special encoder problems.
FALSE
: Data Persistence is not enabled.
TRUE
: Data Persistence is enabled.
