Description

Technical Specifications

  • Input power: three‑phase 230 V AC / 400 V AC
  • Control mode: full‑digital current loop, speed loop, position loop control
  • Feedback interface: resolver feedback interface
  • Communication: RS232, RS485
  • Protection function: over‑voltage, over‑current, short‑circuit, thermal overload protection
  • Ambient operating temperature: 0 °C ~ +45 °C
  • Cooling mode: cabinet natural convection or forced air cooling
  • Mounting method: vertical cabinet wall mounting

Functional Features

High‑dynamic response digital control algorithm; multiple feedback signal support; rich internal motion‑control function block; complete hardware fault protection mechanism; good anti‑interference performance for industrial cabinet environment; supports parameter configuration via PC software.

Application Scenarios

CNC machine tool feed axis, automated packaging machinery, multi‑axis robotic handling equipment, textile high‑speed spindle control, semiconductor processing equipment.

Performance Parameters

Fast current‑loop response; low speed ripple; high position control accuracy; short fault reaction time when over‑current or over‑temperature occurs.

Material Composition

Metal heat‑dissipation housing, power IGBT power module, digital control circuit board, signal interface connector group.

Structural Characteristics

Vertical wall‑mount metal cabinet‑type structure; rear‑side large‑area heat‑dissipation fin; top‑bottom ventilation gap for air convection; front‑side power terminal and signal connector.

Working Principle

Receives position command from upper‑level motion controller; runs digital closed‑loop control algorithm; outputs adjustable three‑phase AC power to servo motor; receives resolver position feedback signal from motor; adjusts output voltage and current in real‑time to realize precise torque, speed and position control.

Installation Requirements

Vertically install inside grounded electrical cabinet; keep sufficient upper‑lower ventilation space for heat dissipation; power cable and encoder feedback cable must use shielded cable; separate power cable from weak‑signal control cable.

Usage Notes

Forbidden to operate with cabinet cover removed; strictly avoid dust accumulation on heat‑dissipation fins; complete parameter matching with matched servo motor before operation; do not touch power terminals within 10 minutes after power‑off for preventing residual electric shock.
