K3: Compensation
5.1 Introduction
Parameterization
These compensation functions can be set for each machine individually with axis-specific
machine data.
Activation
The compensations are active in all operating modes of the control as soon as the input data
are available. Any compensations that require the position actual value are not activated until
the axis reaches the reference point.
Position display
The normal actual-value and setpoint position displays ignore the compensation values and
show the position values of an ideal machine. The compensation values are output in the
"Service axes" display in the "Diagnosis" operating area.
