Working Principle

AC mains input undergoes full-wave rectification to form DC bus voltage; DSP digital processor executes FOC field-oriented control algorithm to output three-phase sinusoidal PWM drive signals to servo motor stator windings. Encoder real-time position feedback forms triple closed-loop control (current-speed-position) to adjust PWM duty cycle dynamically, realizing precise motion trajectory tracking. Regenerative energy from motor deceleration is consumed via internal braking resistor.

Applicable Industries

Small packaging machinery, laboratory automation equipment, PCB micro-positioning stages, textile textile machinery, small laser processing equipment, medical automation test benches, semiconductor micro-handling modules

Installation Requirements

  1. Mount vertically on standard 35 mm DIN rail inside IP54+ electrical cabinet
  2. Maintain minimum 50 mm vertical clearance above/below drive for heat convection
  3. Separate power wiring and encoder signal wiring with shielded cable, minimum 10 cm routing distance
  4. Earth ground terminal must connect to cabinet PE ground with 4 mm² copper wire
  5. Ambient relative humidity limited to 5%–85% non-condensing

Operation Precautions

  1. Power-on sequence: Supply control power first, then main power; power-off sequence reversed
  2. Complete motor auto-tuning before formal load operation
  3. Do not disconnect encoder cable while drive is energized
  4. Avoid operation in dusty, corrosive gas or high-vibration environments
  5. Perform annual insulation resistance test for power terminals to prevent leakage failure
