8. Commissioning

1. Check wiring/insulation before power‑on

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

3. Power on: steady green LED = standby

4. Low‑speed test run; check noise/vibration, then ramp to speed

9. Status & Faults

9.1 LED Indications

• Steady green: Ready

• Flashing green: Running

• Flashing red: Fault

9.2 Common Faults

• Overcurrent: Short circuit, overload, motor fault

• Overvoltage: Supply surge, regenerative voltage

• Overtemperature: Blocked cooling, high ambient

• Communication error: Bad RS‑485 cable, wrong address

10. Maintenance

• Clean heatsink every 6 months

• Check terminal tightness & cable condition

• Replace seals if damaged (maintain IP55)

11. Storage & Disposal

• Store in dry, clean environment within temp range

• Dispose per WEEE regulations; recycle metals, plastics, electronics
