Connecting With Mds-Dm2 Series - Mitsubishi Electric M70V Series Connection Manual

4.2.5.2 Connecting with MDS-DM2 Series

CAUTION
1.Connect the NC and the drive units by the optical communication cables. The distance between the NC and the
final drive unit must be within 30m and the bending radius within 80mm.
2.A spindle drive unit that controls the high-speed synchronous tapping (OMR-DD control) has to be connected
on the farther side from the NC than the subject synchronous tapping control.
Thus, if you use an MDS-DM2 unit for servo control of the high-speed synchronous tapping, combinable
spindle drive is that of the MDS-DM2 unit only.
