• Using a Single-phase, 200-V Power Supply
The Σ-V Series SERVOPACK for a 200-V power supply input has input specifica-
tions for a three-phase power supply, but some models can also be used with a single-
phase 200-V power supply. For details, refer to
Maintenance Rotational Motor/Analog Voltage and Pulse Train Reference (SIEP
S800000 45).
