Working Principle

1. Single-phase 230 V AC mains input rectified to stable DC bus voltage via internal full bridge rectifier module;
2. IGBT power switching module converts DC bus voltage to variable frequency three-phase AC output for driving induction or synchronous servo motors;
3. Internal microprocessor executes sensorless vector control algorithm, calculates motor rotor flux and torque without physical encoder feedback;
4. Digital and analog input terminals receive external PLC speed setpoint signal, PID process feedback signal and equipment safety interlock signals;
5. Integrated brake chopper consumes regenerative energy generated by motor deceleration via external brake resistance to stabilize DC bus voltage;
6. Fieldbus communication interface transmits real-time operating frequency, motor current and fault diagnostic data to upper industrial PLC control system.

• Flying restart function enables smooth motor speed recovery without full stop after momentary power loss
• Built-in motor thermal overload I²t protection curve configurable for different motor insulation classes
• Automatic motor parameter identification function for one-click static motor winding resistance and inductance calibration
• Multi-stage programmable acceleration/deceleration ramps with S-curve soft start/stop to eliminate mechanical shock
• Complete fault protection library: Overcurrent, overvoltage, undervoltage, overtemperature, short-circuit, motor overload, phase loss alarm

Performance Advantages

2. Sensorless vector control achieves full constant torque output at 0.5 Hz low motor speed without encoder feedback;
3. VFC eco energy-saving algorithm reduces idle motor power consumption by up to 30% for conveyor constant speed applications;
4. Integrated PID controller eliminates external independent process PID module for flow/pressure closed-loop control;
5. Built-in brake chopper removes extra braking hardware cost for low-power frequent start-stop machinery;
6. Multi-fieldbus compatibility realizes seamless integration with mainstream Siemens, Rockwell, Beckhoff PLC automation systems.

Applicable Industries

Packaging machinery, food filling production lines, warehouse logistics conveyor systems, plastic extrusion auxiliary equipment, textile processing machinery, small machine tool feed axes, printing paper transport equipment, HVAC industrial fan and pump variable speed control.

Installation Requirements

1. Cabinet mounting vertical installation only, minimum 50 mm top and bottom ventilation clearance for heat sink air circulation;
2. Power and motor wiring must use shielded twisted pair cable, cable shielding grounded at inverter cabinet side only;
3. External brake resistance wiring maximum length limited to 2 m to avoid brake chopper switching interference;
4. Ambient cabinet internal temperature must not exceed 45°C; install forced cooling fan if cabinet heat load exceeds rated dissipation;
5. Signal control wiring routed minimum 10 cm separation distance from high-power motor power cables;
6. Cabinet door must remain closed during operation to maintain IP20 dust protection and EMC compliance.

Usage Precautions

• Forbid operation without ventilation clearance; insufficient heat dissipation triggers overtemperature fault shutdown within 30 minutes continuous full load;
• Motor cable length exceeding 50 m without output filter causes premature IGBT power module breakdown;
• Do not connect single-phase 400 V AC mains input; input voltage overrange permanently damages internal rectifier bridge;
• External brake resistance minimum resistance value cannot be less than 100 Ω; low resistance causes brake chopper overcurrent burnout;
• Storage environment humidity above 95% non-condensing for long periods leads to internal circuit board corrosion and short circuit;
