This bulletin explains how to perform a reset on the Feig encoder when the controller is displaying an F752 or F852-485 encoder faults.
Please Read The Entire Bulletin Before Proceeding
1. Remove the encoder from the drive gear box or motor.
2. Remove the six screws holding the encoder assembly together.
The power MUST be on for the reset to work.
3. Short the two top/left solder dots with a metal screwdriver as shown for a moment.
If the power is on, you will get an error code F766 after shorting the two solder dots.
This shows the reset worked.
4. Reassemble the encoder, and install the six screws removed in the first step.
5. Reinstall the encoder back onto the motor.
6. Clear the F766 fault by holding the reset button.
7. Once you reset the error, you will be prompted to reset limits.
