6.2 PLC Axes

You can assign the controlled axes individually to the PLC.

Remember that:

PLC axes can be operated with following error (also called lag) or with

velocity feedforward control. The axis-specific jerk (MP1097.x and

MP1098.x) is accounted for.

You can start more than one axis simultaneously. However, the axes are not

interpolated with each other.

PLC axes are positioned by the shortest path if you enter a modulo value in

With MP100.x you define for every traverse range which axes the PLC

controls and which the NC controls. Uppercase letters represent NC axes, and

lowercase letters represent PLC axes. To indicate axes that are not present,

mark them with a hyphen "-".
