Working Principle:
The inverter converts three-phase AC input through a rectifier into DC, stored in the DC bus capacitors, then synthesizes variable-frequency PWM output via IGBT switching. In VFC mode, the algorithm continuously calculates a complete motor model to independently regulate flux and electromagnetic torque without encoder feedback. In CFC mode, encoder feedback enables closed-loop current control, where the algorithm decouples the motor’s flux and torque components in real time for independent regulation.

Installation Requirements:

  • Mount vertically inside a control cabinet with adequate ventilation
  • Maintain minimum clearance above and below the unit for airflow
  • Use shielded power and motor cables with 360° shield grounding
  • Motor cable phase sequence must match U-V-W terminal markings
  • Connect braking resistor to dedicated braking terminals (+R, -R) for dynamic braking
  • Ambient temperature must remain within 0°C to +50°C
  • Connect encoder cable to the encoder interface (X15) when operating in CFC mode
  • PROFIBUS-DP cable connects to X30 for fieldbus communication

Usage Precautions:

  • Perform motor initialization after connecting a new motor
  • Use MOVITOOLS MotionStudio software for parameter configuration and commissioning
  • Verify supply voltage stability within ±10% tolerance before operation
  • Never connect or disconnect motor cables while the inverter is energized
  • Monitor fault codes via integrated LED display or MOVITOOLS software
  • Clean heat sink dust regularly; remove immediately if accumulation exceeds 2 mm
  • Confirm grounding resistance is less than 1 Ω
  • Wait at least 5 minutes after disconnecting main power to ensure capacitor discharge before maintenance
  • At 500V supply, system and output current must be derated by 20%
