Fig 4-1-4 Typical main circuit wiring of 220V servo drive
Note:
1. Built-in resistor is default and B2 and B3 terminal is short-circuit. If external resistor is used, please remove the
short cable between B2 and B3, and then connect external resistor between B1 and B2.
2. RLY
：
Alarm-signal output relay.
3. KM1: Contactor, connect or disconnect to main circuit power supply through manual switch.
4. If absolute encoder multi-turn function is adopted, please install battery.
Note: please connect an emergency stop circuit to main circuit so that servodrive can stop and power
off immediately in case accident occurs.
