Cause : PG-F3 Setting Error comes when the encoder signal frequency is too high. With the entered encoder resolution (F1-01), maximum output frequency (E1-04), and motor pole number (E5-04,) the calculation encoder signal frequency exceeds 50 kHz (with PG-F3 option) or 20 kHz (with PG-E3 option).

1. Set F1-01 to the correct encoder resolution.
2. Reduce the maximum output frequency of the drive in parameter E1-04 so the encoder signal frequency at maximum speed is lower than 50 kHz.
