7. Installation & Wiring
7.1 Mechanical Installation
Mount the unit directly on the flange of SEW DRS, DRE or DRP series motors.
Fasten mounting screws with a torque of 3.0 Nm.
Keep the surrounding area well ventilated and stay away from direct heat sources.
7.2 Electrical Wiring
Power Terminals L1, L2, L3, PE: Connect to 3-phase 380–500 V AC power supply and ensure reliable protective earthing.
Motor Terminals U, V, W, PE: Use shielded cables to connect to the motor.
Control Terminals: Connect 24 V DC power, run/stop, direction and enable signals.
Communication Port: Use RS-485 for network connection; install optional Ethernet module for high-end network control.
7.3 EMC Requirements
Use shielded cables for motor and signal lines, and ground both ends of the shield.
Separate power cables and signal cables properly to avoid electromagnetic interference.
8. Commissioning
Inspect all wiring and insulation thoroughly before switching on the power.
Set motor parameters, control modes and communication addresses via DIP switches.
Switch on the main power; steady green LED indicates standby status.
Perform trial operation at low speed first, check for abnormal noise and vibration, then gradually adjust to normal operating speed.
9. Status Indication & Common Faults
9.1 LED Status
Steady green: Unit is ready for operation
Flashing green: Motor is running
Flashing red: Fault alarm triggered
9.2 Typical Faults
Overcurrent: Caused by short circuit, overload or motor winding failure.
Overvoltage: Resulted from abnormal input voltage or regenerative voltage.
Overtemperature: Caused by blocked ventilation or excessive ambient temperature.
Communication error: Due to damaged cables or incorrect communication address settings.
10. Maintenance
Clean dust on the heat sink every six months to guarantee heat dissipation.
Regularly check the tightness of all terminals and the condition of cables.
Replace damaged cables and seals timely to maintain IP55 protection performance.
11. Storage & Disposal
Store the product in a dry and clean environment within the specified temperature range.
Dispose of the product in accordance with local WEEE directives. Sort metal, plastic and electronic components for professional recycling.
