[Key name of the parameter set]
CfgAxisComp
active
The parameter object CfgAxisComp is not required for:
Virtual axes (MP_axisMode=Virtual)
Axes that are for display only (MP_axisMode=Display)
Axis errors are compensated for by changing the command variables for the
position.
The MANUALplus 620 compensates the following mechanically caused axis
errors:
Backlash
Linear axis errors
Nonlinear axis errors (direction-dependent)
• Screw-pitch error
• Axis sag
Thermal expansion
Sliding friction (for digital axes, compensation is carried out in the speed
controller)
You can activate either linear or nonlinear axis-error compensation per axis.
Backlash compensation can be activated in addition to linear axis-error
compensation.
As of NCK software version 597110-04, if nonlinear axis-error compensation
is active, MP_backLash can be used to activate backlash compensation in
addition to the compensation-value tables.
You can also add other types of compensation.

In MP_active, you switch all compensations (except stiction) on or off.
