Troubleshooting: TDU Troubleshooting Tables and Status LEDs
0x14 5 Feedback trip Indicates loss of encoder/resolver feedback and may indicate that
the feedback cable has become detached, one of the signals has
broken, or noise is present.
1. Powercycle the GE T2100 Treadmill and monitor the GE T2100
Treadmill for reoccurrence of this error. (This may be an isolated
incident.)
2. Check the wiring in the Feedback cable.
3. Check the cable screens.
4. Check for damage to the encoder, under the motor cap.
5. Determine if any TDU Troubleshooting Table errors are also
being reported, and if so, follow the troubleshooting procedure
for the reported errors.
6. Replace the drive controller.
0x15 6 Motor overload (I2t) trip The motor overload current protection algorithms have exceeded
their limit and disabled the drive. (The motor / drive can run with
demand currents greater than their rated value for a period of time;
after that time the drive will either trip or automatically foldback the
demand current.)
1. Powercycle the GE T2100 Treadmill and monitor the GE T2100
Treadmill for reoccurrence of this error. (This may be an isolated
incident.)
2. Confirm that the motor is not overloaded or stalling.
3. Determine if any TDU Troubleshooting Table errors are also
being reported, and if so, follow the troubleshooting procedure
for the reported errors.
4. Replace the drive controller.
0x16 7 Over-temperature trip The ambient temperature of the drive controller has exceeded the
trip level, or the Motor overtemperature trip input has been
activated.
1. Allow the unit to cool.
2. Increase ventilation and reduce ambient temperature.
3. Powercycle the GE T2100 Treadmill and monitor the GE T2100
Treadmill for reoccurrence of this error. (This may be an isolated
incident.)
4. Determine if any TDU Troubleshooting Table errors are also
being reported, and if so, follow the troubleshooting procedure
for the reported errors.
5. Replace the drive controller.
