Alarms & Troubleshooting
(10 most important alarms, based on alarm description page 406 of the manual and typical DR series errors; Source: TSE-S800-17D-1.pdf)
Alarms & Troubleshooting
| Code | Designation | Typical Finding | Check | Remedy |
|---|
| A.31 | Overspeed | Motor rotates faster than setpoint | Check feedback | Check parameters & load |
| A.10 | Overcurrent | Overcurrent in output stage | Short circuit U/V/W | Check power section |
| A.30 | Regenerative Error | Regeneration power too high | Measure braking resistor | Reduce load, check RB |
| A.41 | Undervoltage | DC bus too low | Measure supply | Stabilize mains voltage |
| A.40 | Overvoltage | DC bus too high | Overvoltage input | Check mains, check RB option |
| A.51 | Motor Overspeed | Encoder signal faulty | Check encoder & cable | Replace faulty parts |
| A.32 | Overcurrent Protect | IPM/Transistor error | Disconnect U/V/W, test again | Replace Servopack |
| A.71 | Overload High | Axis severely overloaded | Check current profile | Check mechanics, adjust parameters |
| A.72 | Overload Low | Continuous overload | Check work profile | Reduce load |
| A.81 | Encoder Backup Error | Absolute value memory faulty | Check battery/encoder | Change battery, homing procedure |
