5.4.4 400-V Power Supply Voltage
When using SERVOPACK with the three-phase 400-VAC class (380 V to 480 V), prepare the following voltage
conversion transfers (single-phase or three-phase).
When selecting a voltage conversion transfer, refer to the capacities shown in the following table.
* This is the net value at the rated load.
Fig. 5.1 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 the voltage conversion trans-
former.
Voltage conversion transformer inductance will cause a surge voltage if the power is turned ON and OFF at the second-
ary, damaging the SERVOPACK.
