6. Alarm Fault Code Definition (LED Digital Display Code)
| Alarm Code | Fault Description | Solution |
|---|---|---|
| 1 | Overcurrent Fault | Check motor short circuit, main power module damage |
| 2 | Overvoltage Fault | Check input power fluctuation, braking resistor open circuit |
| 3 | Overheat Fault | Clean cooling fan & radiator, reduce continuous load |
| 4 | Encoder Abnormality | Check CN2 encoder wiring breakage or encoder damage |
| A | Parameter Error | Reset factory default parameters and re-set constants |
7. Application Range
8. Maintenance & Storage Note
Regularly clean cabinet dust on drive radiator and built-in cooling fan every 3–6 months; blocked fan will trigger overheat alarm easily
Long-term storage: place in dry & low-humidity environment, avoid dampness and corrosive gas
Warranty: Refurbished unit standard warranty 6 months~12 months; tested used spare warranty negotiable with supplier; matching 100W servo motor, encoder cable and installation backplane available for combined purchase
