3. Controller Functions
Further information about the speed controller and tachometer filter.
Note:
The values given are guide values only. They vary by about 10%
depending on the drive.
3.8 C-Axis Function
At low lathe speeds, the main spindle is used as a servo axis. Contours
can be cut on the workpiece through interpolation with the X-axis.

Figure 50: C-axis on turning machine
The performance of the C-axis largely depends on the stiffness of the
coupling between the motor and the spindle. Maximum stiffness is
obtained with the 1MB frameless spindle motor.
