B.5. 400V Power Supply Voltage
Caution
• Do not connect the servo amplifier directly to any voltage level other than what is specified
on the servomotor.
Doing so will destroy the servo amplifier.
There are 3 types of XtraDrive servo amplifiers. The power supply voltages
are: single-phase 200 V
ac
, three-phase 200V and three-phase 400 V
ac
.
For 200V servo amplifiers that use three-phase 400 V
ac
power supply, prepare
the following voltage conversion transformer (single-phase or three-phase).
Primary Voltage Secondary Voltage
400 V
ac
or 440V 200 V

Refer to the capacities shown in the following table when selecting a voltage
conversion transformer.

IMPORTANT
Turn the power supply ON and OFF at the primary winding of the
voltage conversion transformer when using a 400V class power supply.
Transformer inductance will cause a voltage surge if the power is
turned ON/OFF at the secondary winding, damaging the servo amplifier.
