Note: 1. If the Pr. 903 or Pr. 905 (gain adjustment) value is changed, the Pr. 20 value does not change.
The input signal to terminal 1 (frequency setting auxiliary input) is added to the frequency setting
signal.
2. For the operation procedure using the parameter unit (FR-PU04), refer to the FR-PU04
instruction manual.
Be careful when setting any value other than "0" as the bias frequency at 0V. Even
without the speed command, the motor will start running at the set frequency by
merely switching on the start signal.
