Figure 3‑21 Main circuit wiring of single‑phase 220 V models
Note
● 1KM: Electromagnetic contactor; 1Ry: Relay; 1D: Flywheel diode
● The DO is set as alarm output (ALM+/‑). When the servo drive alarms, the power
supply is cut off automatically. The built‑in regenerative resistor is not available in
models SV660PS1R6 and SV660PS2R8. For these models, you can connect an
external regenerative resistor between terminals P⊕ and C as needed.
● Three‑phase 220 V models: SV660PS7R6I, SV660PS012I
