(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 cable 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
1. 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.
2. If two or more power supply units are connected in the drive system, confirm that the units are not connected with each
other through the L+ and L- lines before turning ON the power. Also make sure that the total capacity of the drive units
connected to the same power supply unit meets the unit's selected capacity.
