The T3D-L20A driver is equipped with protection features that can help diagnose common issues. If an error occurs, the driver's display or your control system may indicate a fault code.
| Symptom/Error | Possible Cause | Corrective Action |
|---|---|---|
| Under Voltage Error | Input power voltage is too low. | Check the 220V AC power supply voltage. Ensure stable power. |
| Over Voltage Error | Input power voltage is too high or regenerative voltage. | Check the 220V AC power supply voltage. Verify braking resistor connection if applicable. |
| Overload Error | Motor load exceeds rated capacity. | Reduce mechanical load or check for mechanical binding. Verify motor sizing. |
| Over Current Error | Excessive current draw, possibly due to short circuit or motor issue. | Inspect motor wiring for shorts. Check motor for damage. |
| Encoder Exception | Encoder signal loss or malfunction. | Check encoder cable connection (CN2). Inspect encoder for damage. |
| Position Error | Motor not reaching commanded position or excessive deviation. | Check mechanical system for binding. Adjust PID gains or tuning parameters. |
For persistent issues or errors not listed, consult the detailed driver manual (if available) or contact RWRAPS technical support.
