Working Principle

AC mains input is rectified to DC bus voltage via internal diode bridge rectifier; 32-bit motion CPU receives motion commands from I/O or onboard program memory, calculates real-time current reference value through triple-loop PID algorithm, outputs PWM signal to drive IGBT power stage to generate three-phase sinusoidal current for permanent magnet servo motor. RS422 differential encoder feeds real-time rotor position/speed signal back to co-processor to form closed-loop feedback regulation, realizing fully automatic position, speed and torque adjustment. Backup lithium battery stores zero-point position data during power outage.

Applicable Industries

Small automated assembly equipment, desktop precision positioning platforms, lab test automation instruments, textile small processing machinery, packaging mini-conveying axes, medical automated diagnostic equipment, electronic component pick-and-place small gantry axes

Installation Requirements

  1. Mount vertically on flat metal cabinet panel; minimum clearance top ≥ 80 mm, bottom ≥ 80 mm, left/right ≥ 50 mm for heat dissipation
  2. Install power line EMI filter on AC input terminal; separate power cable and encoder signal cable routing with metal shielding trunking
  3. Enforce single-point grounding of drive shell to cabinet protective earth with 4 mm² copper ground wire
  4. Operating ambient temperature range: 0°C to +40°C; ambient humidity ≤ 90% RH non-condensing
  5. Installation altitude limit: ≤ 1000 m above sea level; derate output power 6% per additional 1000 m altitude

Usage Precautions

  1. Do not apply 3-phase 380/480 VAC high voltage to single-phase input terminal; permanent power module damage occurs
  2. Replace BR2032 lithium backup cell every 5 years; power off equipment before battery replacement to avoid memory data loss
  3. Tighten all wiring terminals to specified torque value; loose terminals cause overheating and burnout faults
  4. Do not operate under condensation, corrosive gas or conductive dust environment
  5. Complete full parameter auto-tuning after first-time motor wiring modification to prevent oscillation or overcurrent alarm
  6. Store spare unit in dry sealed packaging with desiccant; storage temperature -20°C ~ +60°C
