6. Installation & Wiring

6.1 Mechanical Installation

1. Mount on a rigid, vibration‑free DIN rail or wall.

2. Maintain ≥50 mm clearance around the drive for cooling.

3. Tighten mounting screws to 2.5 Nm.

6.2 Electrical Wiring

1. Power (L1/L2/L3/PE): 3×380–500 V AC, reliable protective earth.

2. Motor (U/V/W/PE): Shielded cable to servo motor.

3. Communication: Ethernet/RS‑485 to controller or PC.

4. STO (Optional): 24 V DC safety signal to STO terminals.

6.3 EMC Guidelines

• Use shielded cables for power, motor, and signal lines; ground shields at both ends.

• Separate power and signal cables by ≥20 cm to reduce interference.

7. Commissioning & Operation

1. Verify all wiring, connections, and insulation before power‑on.

2. Apply main power; green LED indicates standby.

3. Configure parameters, motor data, and communication via SEW MOVITOOLS®.

4. Test run at low speed; check for noise/vibration. Gradually increase to rated speed/load.

5. Monitor operating temperature; keep <70 °C.

8. Maintenance

• Inspect every 6 months.

• Clean dust from vents and fan regularly.

• Check terminal tightness and cable insulation.

• Verify cooling fan operation.

9. Fault Diagnosis

• F01 Overcurrent: Short circuit, overload, or motor fault. Check wiring/load.

• F02 Overvoltage: Supply surge or regenerative voltage.

• F03 Overtemperature: Blocked ventilation or fan failure.

• F04 Comm Error: Cable damage or address mismatch.

10. Storage & Disposal

• Store in a dry, clean environment within temperature limits; keep original packaging.

• Dispose per local WEEE regulations; recycle metal, plastic, and electronics separately.
