7.5.4 Operating Conditions on 400-V Power Supply Voltage

There are three types of SGDH SERVOPACKs, for the power supply voltages: Single-phase 200 VAC, three-
phase 200 VAC, and three-phase 400 VAC. When using the SERVOPACK for 200 V with the three-phase 400-
VAC class (380 to 480 V), prepare the following voltage conversion transformers (single-phase or three-phase)

When selecting a voltage conversion transformer, refer to the capacities shown in the following table.

* This is the net value at the rated load.

Single-phase Power Supply Connection Example

• Do not connect the SERVOPACK for 200 V directly to a voltage of 400 V.

The SERVOPACK will be destroyed.

• Control the AC power supply ON and OFF sequence at the primary side of voltage conversion transfer.

Voltage conversion transfer inductance will cause a surge voltage if the power is turned ON and OFF at the secondary,
damaging the SERVOPACK.
