| E.OU | Overvoltage | Too fast deceleration, high grid voltage, no braking resistor connected | Extend deceleration time, check grid voltage, connect braking resistor |
| E.OL | Overload | Excessive load, mismatched motor, poor heat dissipation | Reduce load, replace matched motor, clean heat dissipation channel |
| E.OH | Overheating | Ambient temperature too high, fan failure, poor ventilation | Lower ambient temperature, replace fan, improve ventilation |
| E.LU | Undervoltage | Low grid voltage, phase loss, power fluctuation | Inspect power grid, repair phase loss, install voltage stabilizer |
| E.GF | Ground Fault | Poor motor grounding, damaged output cable insulation | Check motor insulation, replace output cable |
- Key Operation Precautions
- Installation Requirements
Vertical wall-mounted installation; reserve ≥10cm heat dissipation space top and bottom
Ambient temperature: -10℃ ~ +40℃ (derating required above 40℃)
Avoid installation in dusty, oily, corrosive gas environments
- Commissioning Key Points
Perform motor parameter auto-tuning (Group P09 parameters) for first use
Enter motor nameplate data (rated power, current, speed) under vector control mode
Braking resistor selection: 75Ω/1000W recommended for 5.5kW model, install in well-ventilated area
- Maintenance Suggestions
Regularly clean cooling fan and filter (every 3~6 months)
Check main circuit terminal tightness (every 6 months)
Perform insulation test if stored unused for more than 6 months
- Selection & Replacement Guideline
- Existing Equipment Maintenance: Prioritize original refurbished or dismantled spare parts for cost performance.
- New Project Design: Strongly recommended to replace with Lenze i550 series for better performance and lower maintenance cost.
- Replacement Steps
Confirm motor parameters (power, voltage, current, speed)
Match replacement model rated output current (≥11.5A)
Retain original control circuit wiring; only minor parameter modification needed
Complete motor auto-tuning to ensure control accuracy
