5.5 Rotary Axis Roll-over
This function can be used in case of rotary axes, i.e., if address A, B or C is selected for operating
rotary axis. Handling of roll-over means, that the position on the given axis is not registered between
plus and minus infinity, but regarding the periodicity of the axis, e.g., between 0/ and 360/.
Selecting rotary axis
The selection can be executed by setting parameter 0182 A.ROTARY, 0185 B.ROTARY or 0188
C.ROTARY to 1 for axes A, B or C, respectively. If among these parameters one is set to 1
– the control does not execute inch/metric conversion for the appropriate axis,
– roll-over function can be enabled for that axis by setting the appropriate parameter ROLLOVEN
to 1.
