7. Installation & Wiring

7.1 Mechanical

1. Mount directly to SEW DRS/DRE/DRP motor flange

2. Tighten screws to 3.0 Nm

3. Ensure free airflow around heat sink; avoid direct heat sources

7.2 Electrical

1. Power: L1/L2/L3/PE → 3×380–500 V AC (good earth)

2. Motor: U/V/W/PE → shielded cable to motor terminals

3. Control: 24 V DC for run/stop, direction, enable

4. Communication: RS‑485 for Modbus RTU (optional)

5. Brake: Integrated control for SEW brake motors (if used)

8. Commissioning

1. Check wiring & insulation before power‑on

2. Set motor parameters, I/O logic, & address via DIP switches

3. Power on: steady green = standby

4. Test at low speed; check noise/vibration, then ramp to operating speed

9. LED Status & Faults

9.1 LED

• Steady green: Ready

• Flashing green: Running

• Flashing red: Fault

9.2 Common Faults

• Overcurrent: Short circuit, overload, motor fault

• Overvoltage: Input surge or regenerative voltage

• Overtemperature: Poor ventilation or high ambient temp

• Comm error: Cable fault or wrong address

10. Maintenance

• Clean heat sink every 6 months

• Check terminal torque & cable condition regularly

• Replace damaged seals to maintain IP55

11. Storage & Disposal

• Store dry, clean, within temp limits

• Dispose per local WEEE; recycle metal, plastic, electronics
