(3) When using one power supply shared unit by two NC communication bus systems
In systems employing a number of small-capacity drive units, a single power supply unit can be shared by two NC
communication bus systems. In this case, a power supply control axis must be set for each axis of each NC
communication bus.
For basic connection information, refer to the MDS-D/DH Series Instruction Manual.

Connections when using one power supply shared by two NC communication bus systems
If the two NC communication bus systems include a spindle drive unit, connect the power
CAUTION supply unit's CN4 connector to the CN4 connector of the largest capacity spindle drive unit. If
there is no spindle drive unit, connect to the unbalance-axis servo drive unit.
