Preface
Introduction
Thank you for purchasing the SV670P series servo drive developed by Inovance.
The SV670P series servo drive is a high‑end servo drive designed based on global‑
leading standards and high‑end application needs. It is featured with high speed, high
precision, high performance, and tuning‑free Function.
The servo drive covers a power range from 0.05 kW to 7.5 kW and carries Modbus
communication interfaces to work with the host controller for a networked operation
of multiple servo drives. The drive comes with the ITune function which supports
adaptive stiffness level setting, inertia auto‑tuning, and vibration suppression for easy
use. The servo drive, together with an MS1 series high‑response servo motor (with
ultra‑low, low or medium inertia) equipped with a 23‑bit single‑turn/multi‑turn
absolute encoder, serve to deliver a quiet and stable operation and accurate process
control through the fully closed‑loop function and internal process segment function.
The drive also offers dynamic braking. The drive aims to achieve quick and accurate
position control, speed control, and torque control through high‑performance
solutions for automation equipment in such industries as electronic manufacturing,
lithium batteries, manipulators, packaging, and machine tools.
This guide provides instructions on maintenance and repair of the equipment.
