2-5-3 Using multiple power supply units
In a system configured of multiple spindle drive units, etc., there may be cases when the drive capacity
is large and the units cannot be driven with one power supply unit. Split the drive configuration so that
the units can be driven with one power supply unit.
Refer to section "11-7 Selecting the power supply unit" for details on making a selection.

CAUTION
1. An AC reactor and breaker must be installed for each power supply unit.
The connection of the communication cable to the NC does not change.
(Refer to section "2-3 NC and drive unit connection")
2. When distributing and installing the units, always arrange the power supply
unit and spindle drive as a set. Keep the total length of the TE2 wire as short
as possible (50cm or less).
