6. Installation & Wiring

6.1 Mechanical Installation

1. Mount the drive on a rigid and vibration-free DIN rail or wall.

2. Keep a minimum clearance of 50 mm around the unit for heat dissipation.

3. Tighten mounting screws to a torque of 2.5 Nm.

6.2 Electrical Wiring

1. Power Terminals (L1, L2, L3, PE): Connect 3-phase main power supply and ensure reliable protective earth connection.

2. Motor Terminals (U, V, W, PE): Connect to the servo motor with shielded cables.

3. Communication Ports: Connect Ethernet or RS-485 interface to controller or commissioning PC.

4. STO Interface (Optional): Wire 24 V DC safety signal to the STO terminal.

6.3 EMC Requirements

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

• Separate power cables and signal cables with a distance of no less than 20 cm to avoid interference.

7. Commissioning & Operation

1. Pre-check all wiring, connections and insulation before power-on.

2. Switch on the main power; the status LED turns green for standby mode.

3. Complete parameter configuration, motor data setting and communication setup via SEW MOVITOOLS® software.

4. Perform trial run at low speed first, check for abnormal noise and vibration. Gradually increase speed and load to rated values.

5. Monitor operating temperature during operation; normal temperature shall not exceed 70 °C.

8. Maintenance

• Conduct routine inspection every 6 months.

• Clean dust on cooling vents and fan regularly.

• Check tightness of all terminal connections and cable insulation.

• Verify normal operation of the cooling fan.

9. Common Fault Diagnosis

• F01 Overcurrent: Caused by short circuit, overload or motor failure. Check wiring and load condition.

• F02 Overvoltage: Abnormal supply voltage or regenerative voltage surge.

• F03 Overtemperature: Blocked ventilation or cooling fan malfunction.

• F04 Communication Error: Damaged communication cable or inconsistent station address.

10. Storage & Disposal

• Store the product in a dry and clean environment within the specified temperature range. Keep original packaging during storage.

• Dispose of the product in accordance with local WEEE directives. Sort metal, plastic and electronic components separately for professional recycling.
