2.3 NC and Drive Unit Connection
2.3.1 Connection of Optical Communication Cables
Connect the optical communication cables from the NC to the each drive unit so that they run in a straight line from the
NC to the drive unit that is a final axis. And up to 16 axes can be connected per system.
Note that the number of connected axes is limited by the NC.
(1) 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.
< Connection >
CN1A : CN1B connector on NC or previous stage's drive unit
CN1B : CN1A connector on next stage's drive unit
CN4 : Connector for communication between power supply unit (master side) and drive unit
Connection when using one power supply unit
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 specified bending radius (for wiring inside panel: 25mm, and for wiring outside
panel: 50mm) or more.
2. For the main circuit wiring of the drive unit and power supply unit, the drive unit of 200V series is to be wired with MDS-
D2-CV, and the drive unit of 400V series is to be wired with MDS-EH-CV.
POINT
Axis Nos. are determined by the rotary switch for setting the axis No. (Refer to section "Setting the rotary switch".) The axis
No. has no relation to the order for connecting to the NC.
