6.4.7 Operating Conditions on 400-V Power Supply Voltage
There are four types of SGDM SERVOPACKs, for the power supply voltages: Single-phase 100 VAC, single-
phase 200 VAC, and three-phase 200 VAC. When using the SERVOPACK for 100 V or 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 100 V and 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.
