Cause : PG-F3 Setting Error comes when the entered encoder resolution (F1-01), maximum output frequency (E1-04), and motor pole number (E5-04), the calculation encoder signal frequency exceeded 50 kHz (with PG-F3 option).

  1. The encoder signal frequency is too high.
  2. Set F1-01 to the correct encoder resolution.
  3. 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.
