(2) When using two or more power supply units within a single NC communication bus system
Two or more power supply units may be required within a single NC communication bus system if
the spindle drive unit capacity is large. The drive unit receiving power (L+, L-) from each power
supply unit must always have NC communication bus connection at the NC side of each power
supply unit. In the NC communication bus connection example below, power supply [1] cannot
supply power (L+, L-) to the 5th axis servo drive unit.
For basic connection information, refer to "(1) When using one power supply unit".

CAUTION
The drive unit receiving power (L+, L-) from each power supply unit must always
have NC communication bus connection at the NC side of each power supply
unit.

(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 "(1) When using one power supply unit".

CAUTION
If the two NC communication bus systems include a spindle drive unit, connect
the power 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.
