Checking the states of axis compensation in the NC program

V.A variables

The following V.A. variables can be used to check from the NC program whether a compensation programmable via the COMP command is initialised or already active for a specific axis.

Initialisation check

V.A.Compensation name_INIT[Achsindex] or

V.A.Compensation name_INIT.Achsname

Activation check

V.A.Compensation name_ACTIVE[Achsindex] or

V.A.Compensation name_ACTIVE.Achsname

The following identifiers are available for compensation name.

CROSS_COMP for cross compensation

PLANE_COMP for plane compensation

LEAD_COMP for leadscrew error compensation

TEMP_COMP for temperature compensation
