# Selecting/activating the machine coordinate system (#CS SELECT[MCS])

A kinematic transformation when activated generates a predefined machine CS. The origin of this CS is at the machine zero point and it is assigned the fixed name of MCS. It may be used in combination with the selection command #CS SELECT. If a user-specific CS is programmed with this name via #CS ADDm an error message is output.

Syntax of Selecting/activating a predefined MCS:
#CS SELECT [MCS]

Activate machine CS with #CS SELECT [MCS]

## Notice

Limit #CS SELECT[MCS] and #MCS ON

The command #CS SELECT [MCS] activates the first Cartesian CS at the machine zero point when a kinematic transformation is active.

By contrast, the command #MCS ON deactivates all active Cartesian and kinematic transformations and offsets to permit the machine axes to be positioned directly.
