Programming tool lift-off with FUNCTION LIFTOFF

Requirement
Refer to your machine manual.
This function must be configured and enabled by your
machine manufacturer. In machine parameter CfgLiftOff
(no. 201400), the machine manufacturer defines the path
the tool is supposed to traverse for a LIFTOFF command.
You can also use machine parameter CfgLiftOff to
deactivate the function.
In the LIFTOFF column of the tool table, set the Y parameter for the
active tool.

Application
The LIFTOFF function is effective in the following situations:
In case of an NC stop triggered by you
In case of an NC stop triggered by the software, e. g. if an error
has occurred in the drive system.
In case of a power interruption
The tool retracts from the contour by up to 2 mm. The control
calculates the lift off direction based on the input in the FUNCTION
LIFTOFF block.
You can program the LIFTOFF function in the following ways:
FUNCTION LIFTOFF TCS X Y Z: Lift-off in the tool coordinate
system (T-CS) with the vector resulting from X, Y and Z
FUNCTION LIFTOFF ANGLE TCS SPB: Lift-off in the tool
coordinate system (T-CS) with a defined spatial angle
Lift-off in the tool axis direction with M148
