Technical Manual for EA350 Analog Pulse Type Servo Driver V101 3.2.2 Power wiring The servo driver may be subject to single-phase or three-phase power wiring. Single-phase power wiring is only permitted for models with the output current of 6.2A or below. Single-phase power wiring (applicable to drivers with a rated output current of 6.2A or below) Fig. 3-1 Single-phase power wiring diagram Three-phase power wiring (applicable to drivers with a rated output current of 4.8 A to 28 A) Fig. 3-2 Three-phase power wiring diagram (4.8 - 28 A) Caution ☞ 1. If you don’t wish to cut off the power of the main circuit upon an alarm, the RA relay is not needed. 2.
L1C and L2C may be connected to P+ and - terminals respectively (despite of polarity) instead of an external power supply. Three-phase power wiring (applicable to rated output current of 38A or above) Fig. 3-3 Three-phase power wiring diagram (above 38 A) 25
