(2) System establishment in the synchronous control
(a) Position command synchronous control
The synchronous control is all executed in the NC, and the each servo is controlled as an independent
axis. Therefore, preparing special options for the synchronous control is not required on the servo side.
(b) Speed command synchronization control
The common position control in two axes is performed by one linear scale. Basically, the two axes
integrated type drive unit (MDS-D/DH-V2) is used, and the feedback signal is divided for two axes inside
the drive unit.
When the two 1-axis type drive units are used in driving the large capacity servomotor, the linear scale
feedback signal must be divided outside.
<Required option in the speed command synchronous control>
(Note) The rectangular wave signal output scale speed command synchronous control is not available.

When executing the synchronous control, use the servomotors of which the type and detector
specifications are same.
