13 Spindle Control

13.6 Spindle-Mode Servo Motor Control

This function controls a spindle using the combination of servo motor and servo drive unit (MDS-E Series) which controls NC

The maximum rotation speed of servo motor is low compared with a spindle motor. However, if the rated output is the same,

the machine components can be downsized by using a servo motor to drive tool spindle, etc, because the servo motor is

smaller than the spindle motor.

Note that some spindle functions can not be used under the spindle-mode servo motor control.

The figure below is the example of the application.

Normally, the components "spindle drive unit + spindle motor" are needed when cutting, drilling or milling is performed on a

lathe with turret type tool selection mechanism, which means two pairs of "spindle drive unit + spindle motor" are needed; one

for a main spindle and one for a turret. Therefore, including the main spindle, two sets of spindle drive and spindle motor are

However, downsizing of the turret, space-saving of the lathe and cost reduction can be achieved by replacing the turret side

spindle drive with a servo motor and using spindle-mode servo motor control.
