1 Brief description

Aim of the module:

In this module you learn how to switch on the machine and/or the control unit and how to approach

the reference point of the axes.

Description of the module:

Both the machine and the control unit must be switched on before any work can be done on the ma-

chine. Following this all axes with incremental measuring systems must be referenced in order to en-

able the control unit to establish the position of the axes within the machine coordinate system.

There is no need to reference any axes equipped with absolute measuring system. In this case the

control unit recognizes the position of the axes automatically.
