Working Principle

Advantage Highlights

1. All core functional modules (braking, EMC filter, STO safety) integrated as standard configuration, no extra accessory purchase required
2. High starting torque sensorless vector control eliminates expensive encoder installation cost for most transmission equipment
3. Wide ambient temperature and altitude adaptation range, suitable for outdoor mining, water treatment and agricultural machinery harsh environments
4. One-click motor self-tuning and parameter copy functions greatly shorten on-site equipment commissioning time
5. High energy conversion efficiency reduces long-term industrial operation power consumption cost

Applicable Industries

Installation Requirements

1. Vertical installation only, mounting inclination angle cannot exceed 10°, horizontal installation strictly prohibited
2. Maintain ≥ 150mm vertical heat dissipation gap above and below the drive, ≥ 50mm horizontal gap between adjacent drives
3. Input power cable uses shielded copper cable, motor output cable must be shielded cable with shielding layer double-ended grounding
4. Install external braking resistor when braking duty cycle exceeds 10% continuous operation
5. Cabinet cooling fan required when multiple drives are installed in single cabinet to control internal temperature below 50°C

Usage Precautions

1. Do not operate drive without connecting motor load, no-load operation may damage output IGBT module
2. STO safety circuit wiring must use dedicated safety cable, no shared wiring with ordinary control signals
3. Clean heat sink dust filter screen every 3 months for dusty industrial workshop environments
4. Avoid frequent repeated start-stop operation exceeding 20 times per minute to prevent overheating power module
5. Cut off input AC power supply and wait minimum 10 minutes for DC-link capacitor discharge before opening drive housing maintenance
