1.Main Functions

1. Three‑loop closed‑loop motion control (current‑speed‑position loop) Ultra‑fast 4.5 kHz current‑loop bandwidth, 3 kHz speed‑loop bandwidth. Supports three core control modes: cyclic‑synchronous position (CSP), cyclic‑synchronous velocity (CSV), cyclic‑synchronous torque (CST). Receives motion commands from EtherCAT master, outputs three‑phase AC power to servo motor. Realizes high‑precision position locating, speed adjustment and torque‑limited output for automation axes.
2. EtherCAT high‑speed field‑bus communication Implements EtherCAT protocol with distributed clock function; multi‑axis synchronization accuracy down to 15 ns. Supports standard CoE (CANopen over EtherCAT) object dictionary. Realizes cyclic command transmission, actual‑value feedback, parameter read‑write and alarm reporting between upper‑level controller and multiple servo drives. Daisy‑chain wiring simplifies multi‑axis system layout.More products: www.plcva.com
3. Absolute encoder feedback processing Receives serial feedback signal from 23‑bit single‑turn / multi‑turn absolute encoder. Reads absolute rotor position directly upon power‑on; eliminates mandatory homing procedure after power‑off‑and‑restart. Completes closed‑loop position calculation inside drive and monitors encoder communication health status

INOVANCE SV660NS2R8I AC Servo Drive

1. Auto‑tuning and vibration‑suppression algorithms Built‑in STune / ETune one‑click inertia auto‑tuning function. Automatically identifies load inertia ratio and optimizes servo gain parameters. Equipped with notch filter and vibration‑suppression algorithm to suppress mechanical resonance and low‑frequency oscillation, improving motion smoothness and reducing commissioning workload on site.
2. Multi‑channel digital & analog I/O interface Configurable 8‑point fast digital inputs and 4‑point digital outputs. Supports limit switch signals, home‑switch input, servo enable, brake control output, servo ready and fault‑alarm output. Analog input/output channels are available for torque or speed reference. Supports hardware position‑capture function for high‑speed trigger applications such as flying‑shooting.
3. Comprehensive hardware protection and status diagnosis Integrated multi‑protection mechanisms: over‑current, over‑voltage, under‑voltage, over‑heat, output short‑circuit, encoder‑abnormality, overload and regenerative‑overvoltage protection. Five‑digit LED display and local operation keys show real‑time running status, fault codes and parameter values. Stores fault history records for troubleshooting. Supports external STO (Safe Torque Off) safety signal interface for safety‑related machine requirements
4. Industrial mechanical & environmental adaptability Compact base‑plate mounting structure for cabinet installation. Operating temperature: 0 °C ~ +55 °C. High anti‑vibration and EMC immunity performance for industrial cabinet environment. Supports external regenerative resistor connection for handling regenerative energy during frequent deceleration of vertical axes.
