Check These Items
The drive 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. Verify connections to braking resistor are not damaged.
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.
Position or velocity following error. Following errors could be
caused by a badly tuned drive controller/motor, especially at high
acceleration and deceleration rates where the following error will
typically be greater. Following error could also be the caused by
encoder/resolver loss.
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.
Indicates a user-defined condition has been activated and
generated an error.
1. Powercycle the GE T2100 Treadmill and monitor the GE T2100
Treadmill for reoccurrence of this error. (This may be an isolated
incident.)
2. Determine if any TDU Troubleshooting Table errors are also
being reported, and if so, follow the troubleshooting procedure
for the reported errors.
3. Replace the drive controller.
The drive controller has a pre-charge circuit which must activate
after power-up before the drive controller can be enabled. If the
drive controller is enabled before this, then the error occurs. The
error could also indicate the loss of one or more of the input
phases.
1. Powercycle the GE T2100 Treadmill and monitor the GE T2100
Treadmill for reoccurrence of this error. (This may be an isolated
incident.)
2. Determine if any TDU Troubleshooting Table errors are also
being reported, and if so, follow the troubleshooting procedure
for the reported errors.
3. Replace the drive controller.
