What does 10039 mean?
An error has occurred when using the Resolver Adapter (OPT-MF-201 or FB-03) due to a loss of resolver signals. This typically indicates an issue with the wiring to the motor's feedback device, the integrity of the motor connector, or the connections inside the adapter itself, preventing accurate position feedback and control.
