2.1.5 Servo motor and AC power supply wiring diagrams
1. The power supply for the servo driver EP3-GL series is a three-phase AC 220V which
generally come from three-phase AC380V power supply through a transformer. In peculiar
circumstance, the small servomotor, which is less than 750W, can use single-phase AC220V
(L1 and L2 terminals connect to single-phase power supply. Leave L3 terminal alone).
