5.8.5 400V Power Supply Voltage
There are four types of SGDH servo amplifiers. The power supply voltages are:
single-phase 100V
ac
, three-phase 200V
ac
, single-phase 200V
ac
and three-phase
400V
ac
. For 100V and 200V servo amplifiers that use three-phase 400V
ac
power
supply, prepare the following voltage conversion transformers (single-phase or
three-phase).
Refer to the capacities shown in the following table when selecting a voltage
conversion transformer.
• Do not connect the servo amplifier directly to any voltage level other than what is specified on the ser-
vomotor.
Doing so will destroy the servo amplifier.
