Programming

<Axis_name> [ DIST_CTRL [ON | OFF] | [CHECK_POS | FREEZE | REF] SET_POS<expr> [VAL1<expr> -VAL5<expr>] ]

<Axis_name> Name of the axis carrying the tool

DIST_CTRL Identifier for the "sensed spindles" functionality. This must always be programmed as the first key word.

ON Activate distance control. A set position (SET_POS) must be set before activation

OFF Deactivate distance control.

CHECK_POS Check whether position is in the tolerance window.

FREEZE Freeze the control distance over the workpiece. The axis position or the output correction value is maintained, i.e. readjustment of the axis depending on the workpiece surface is interrupted.

REF Measurement system (sensor) referencing (only if there is no absolute measuring system)

SET_POS<expr> Specification of the workpiece surface [mm] (absolute position). At the end of the program or in the event of a reset, the set position is reset, i.e. a new set position must be specified before distance control is activated.

VAL1<expr>-VAL5<expr> Freely assignable values (5)

The key words ON/OFF, FREEZE, CHECK_POS and REF are mutually exclusive in the same command. The key words SET_POS and VAL1-VAL5 can always be included in the programming in combination. If the function is still active at the end of the program, it is cancelled automatically (implicit "OFF").
