Fanuc A860-2020-T321 BETA i encoder. These BiA128 encoders fit on Fanuc Bi series servo motors. From series model ai2 on wards, thru bi4, bi8, bi12, bi22 and other variations of BETA i servo motors. Stocks are always low on this particular type of Fanuc encoder and hence availability changes day by day; as we require encoders to repair motors, etc.
DNC offer exchange A8602020T321 BETA absolute encoders for your servo motor. Further we can also offer fault testing and diagnosis, via our static testing machine and then onto our 0i-MC, 0i-MD, or 31i-MA test rigs dependent on whats available. Due to the way Fanuc has manufactured these encoders, they are very seldom repairable – regardless of the many claims that you find from other companies. If you are unsure whether your Fanuc servo motor or your B128iA encoder is faulty ship the motor to us for inspection and test.
