Main circuit single-phase/three-phase 220 V power input. Terminals L1
and L2 are for single-phase power input, and terminals L1, L2 and L3
are for three-phase power input.
Control circuit 220 V AC power input.
When large-inertia load needs braking for emergency stop, connect an
external bleeder resistor between P and C.
The external bleeder resistor needs to be purchased additionally.
They are used for common DC bus connection when multiple servo
drives are under parallel control.
Two grounding terminals of the servo drive are respectively connected
to those of the power supply and the servo motor.
