Commissioning the PLC axis
The PLC can control axes/spindles via data blocks of the PLC user interface. The PLC axis can be used for turret/magazine
control or workpiece transfer on a turning or milling machine.
There are three positioning modes for the PLC axis:
● Positioning via the PLC user interface
● Positioning with the indexing position table predefined in the general machine data
● Positioning according to the distance value defined in the axis machine data
