| Fanuc 6T Error Details |
|---|
| Item | Cause | Check procedure | Countermeasure |
| 1 | Overload | Check that the motor armature current exceed the rated current. | Decrease the load torque.
Decrease the cutting duty. |
| 2 | Winding insulation trouble | Check the insulation between motor power and the terminals A1 or A2 and the motor bodys with a tester or a megger. Over 1Meg. Ohm at 500 volts is normal for the megger check. Infinite value is normal in the tester check. | Clean around the communicator with forced air.
Change the motor if the above countermeasure is ineffective. |
| 3 | Short circuit in the internal wiring | Measure no-load current by removing the motor from the machine. If the current increases in proportion to the motor rotation rate, there is a short circuit in the internal wiring. | Clean around the communicator. The oil adheres to the surface of the communicator, this problem can easily occur. |
| 4 | Field system magnet demagnetized | Check that voltage is normal by measuring the motor terminal voltage between terminals A1 and A2. | Change the motor if terminal voltage is low or the motor is overheated. |
| 5 | Trouble in the heat pipe fan operation | Check the fan voltage or the wiring
Check whether the fan touches a wire gauze
Check the fan motor. | Rearrange the wiring.
Refix the wire guage.
Replace the fan motor. |
| 6 | Trouble in heat pipe efficienty | The heat pipe is ineffective, the attached motor is overheated, despite that all the above items concerning the trouble in the heat pipe fan operation are normal. | Replace the motor. |
| 7 | Brake trouble | Check that the brake connection corresponds to the power source frequency.
Check that the voltage is 100V +- 10% (allowable value) | Replace the brake. |
| 8 | Connection trouble | Check whether a motor signal line is disconnected or a connector is loose. | Replace the fault. |
