3.6 Spindle Positioning

Three standard spindle positions can be set for the drive via the controller

for simple and rapid tool change on milling centers.

If more than three positions are required, for example,

• for aligning the tool to the workpiece contour on milling machines,

• indexing the workpiece on lathes, or,

• positioning workpieces for balance holes on balancing machines,

then 3600 optional selectable spindle positions are available.

The position command values can be accurately set to 0.1 angular

degrees and are corrected to a maximum of 1/1000th of an angular

degree.

Three modes of mechanical coupling between motor and spindle make

different types of positioning possible.
