<Adjustment procedure> Pr. 902 (Pr. 904) "frequency setting voltage (current) bias"
• When operation panel (FR-DU04) is used
(1) Any point is adjusted with
a voltage (current) applied
Apply the bias voltage (current).
*Pr. 903 to Pr. 905 can also be adjusted similarly using the above procedure.
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.

across terminals 2(4)-5 is displayed.
(2) Any point is adjusted with
no voltage (current) applied
Using the [UP/DOWN] key, set
the bias voltage (current) in %.
[0% for 0V (0mA), 100% for 5V
(10V, 20mA)]
Press the [SET] key for about 1.5 seconds.
The bias voltage (current) setting flickers.
Bias setting complete.
Press the [SET] key.
