80mm.
Axis Nos. are determined by the rotary switch for setting the axis No. (Refer to the MDS-D/DH
POINT
Series Instruction Manual.) The axis No. has no relation to the order for connecting to 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.
