# Offset types

## Overview of clamp position offsets that are selectable in parallel:

Overview of all offset types

## Notice

Special case in G91 mode:

Newly selected offsets are only effective after the next absolute programmed position (G90) since only the specified motion path may only be travelled in the case of relative programming (G91).

Tool offset exception: With appropriate parameterisation, tool offsets are travelled directly without programming a path movement when the D word (P-CHAN-00100) is selected.

## Differences in definition and selection of individual offsets

Differences and selection of offsets

Offsets are selected or included in calculations by the following NC commands or parameters:

NC command | Description
#CS, #ACS, #ECS, #ROTATION | Select a coordinate system : : Rotate in the plane
G101 | Include measuring offset in calculations
G201 #GET MANUAL OFFSETS | Include manual mode offsets in calculations
#PSET | Select position presets
G92 | Reference point offset
G54, ... G59, G159 | Select zero offsets
D | Tool geometry compensation

Variable | Description
pzv_index | Index for selecting position offset. This must be specified along with the NC program name when an NC program is commanded.
