Working Principle: Three-phase fixed frequency AC input power passes through rectifier bridge to convert into DC power. DC bus voltage is filtered by DC capacitors. IGBT inverter module converts DC power into variable frequency three-phase AC output to drive induction motor. The control board calculates output voltage and frequency according to speed reference signal. Vector control algorithm estimates motor rotor flux and speed to adjust output current for high torque performance. Protection circuit monitors current, voltage and temperature continuously.
Installation Requirements:
- Mount inverter vertically inside well ventilated electrical cabinet
- Maintain specified clearance above and below unit for air flow
- Install input circuit breaker and motor output cable with proper shielding
- Separate motor power cable from control signal cables
- Implement reliable protective earth connection
- Keep ambient temperature below +40 °C, avoid direct sunlight
Usage Notes:
- Complete motor nameplate parameter setting before commissioning
- Do not run inverter without motor connected for long time
- Check heat sink and fan dust filter periodically
- Disconnect AC input power and wait for DC bus discharge before opening cabinet
- Verify motor insulation resistance before connecting to inverter
- Avoid frequent start-stop operation exceeding rated capability
