Practical Troubleshooting for HLPA03D723B (3.7kW/220V)
- Fault Codes (Most Common)
1.1 OC / Overcurrent
Causes: Motor jam, shorted cable, fast acceleration, poor motor insulation
الحلول:
- Check for seized motor or overload
- Increase acceleration time
- Inspect U/V/W cables for damage or short
- Run inverter without motor to isolate fault
1.2 OV / الجهد الزائد
Causes: Fast deceleration, high mains voltage, high-inertia load
الحلول:
- Increase deceleration time
- Add external braking resistor (≈50Ω/100W)
- Check if input exceeds 250 V
1.3 UV / انخفاض الجهد
Causes: قليل 220 V, loose wiring, phase loss
الحلول:
- Measure R/S/T voltage (no lower than 180 V)
- Tighten power terminals
- مرحلة واحدة: connect R & S only
1.4 OH / Overheat
Causes: Blocked vents, faulty fan, high ambient temp
الحلول:
- Clean heatsink and fan
- Verify fan operation
- Maintain ≥10 cm clearance top/bottom
1.5 OL / Motor Overload
Causes: Heavy load, wrong motor parameters, low torque
الحلول:
- Reduce load
- Check motor rated current setting
- Increase torque boost
1.6 GF / Ground Fault
Causes: Motor leakage, grounded cable, poor insulation
الحلول:
- Test motor insulation
- Check output cable for grounding
- Secure PE connection
1.7 م / Communication Error
Causes: RS485 interference, wrong wiring
الحلول:
- Check A/B wiring polarity
- Use shielded cable, grounded at one end
- Route away from power cables
- Abnormal Operation (No Fault Code)
2.1 Keypad displays but motor does not run
الحلول:
- Check if in terminal control, no start signal
- Verify DI1 (FWD) is closed
- Check frequency reference (0 V/0 mA)
2.2 Motor vibration / ضوضاء
الحلول:
- Lower carrier frequency
- Tighten motor cables
- Increase torque boost at low speed
2.3 Frequency cannot rise / limited
الحلول:
- Check maximum frequency parameter
- Verify analog signal (0‑10 V/4‑20 mA)
- Check for false multi-speed input
- Important Notes for HLPA03D723B
220 V ONLY: DO NOT connect to 380 V (will damage IGBT module)
قمة 3 أخطاء: OC, OV, UV
Single-phase input must be tightly secured; loose terminals often cause UV faults
