# Parameters

The touch probe must be configured in addition to supplying the input parameters described here. For more information on this function, see the section Configuration file.

The (calibrated) parameters of the touch probe (radius, length and offset in X and Y directions) are specified via the tool parameters.

## Required input parameters

Input parameters | Description
@P2 | Spigot diameter
@P19 | Pre-position along the Z axis

## Optional input parameters

Input parameters | Description
@P7 | Zero offset to be described (TCS) G159=1 to G159=9 and G54 to G59 Input without address "G159=" or "G" If not specified, then measurement only but no write function Only permitted when G53 is active at cycle call.
@P9 | Shift the measuring point along the X axis
@P10 | Shift the measuring point along the Y axis
@P13 | Safety clearance for pre-positioning [mm, inch] Default value = diameter of touch probe
@P14 | Angle 1 to first measuring point in relation to X+ axis [degrees] Default value = 0
@P15 | Angle 2 to second measuring point in relation to X+ axis [degrees] Default value = 120
@P16 | Angle 3 to third measuring point in relation to X+ axis [degrees] Default value = 240
@P33 | Crossover range (unsigned) [mm, inch] Default value = 5

Angles 1-3 must be different.

It is recommended to use the Syntax check.to verify whether the input parameters are correctly assigned.
