(7)Re-set the Pr. 79 "operation mode selection" value according to the operation mode being used.

CAUTION

1.Changing the Pr. 903 or Pr. 905 (gain adjustment) value will not change the Pr. 20 "acceleration/decel- eration reference speed" value. (Refer to page 54 for Pr. 20.) The input of terminal 1 (speed setting auxiliary input) is added to the speed setting signal.

2.For the operation procedure using the parameter unit (FR-PU04V), refer to the FR-PU04V instruction manual.

3.When applying voltage for calibration, the difference of the set input voltage of bias and gain should be 5% or more. If the difference is 5% or less, a setting error will occur.

CAUTION

Take care when setting any value other than "0" as the bias speed at 0V. Even if a speed command is not given, merely turning on the start signal will start the motor at the preset speed.
