7.6.1 Connecting with Drive Unit MDS-E/EH Series

7.6.1.1 Connection of Optical Communication Cables

CAUTION
(1) Connect the NC and drive units with the optical communication cable. The distance between the NC and final
drive unit must be within 30 m and the specified bending radius (for wiring inside panel: 25 mm, and for wiring
outside panel: 50 mm) or more.
(2) For the main circuit wiring of the drive unit and power supply unit, wire 200 V series drive units with MDS-E-CV
and 400 V series drive units with MDS-EH-CV.
POINT
Axis Nos. are determined by the rotary switch for setting the axis No. (Refer to the drive unit manual.)
Axis No. is unrelated to the order for connecting to the NC.
When Using One Power Supply Unit
Connect the largest-capacity spindle drive unit to the final axis of the NC communication bus in order to control the power
supply unit. The spindle drive unit must be installed adjacent to the power supply unit. In the system with servo only, a servo
drive unit for controlling unbalance axis must be installed in the same manner in the same way.
