When the set frequency (speed) is 100 or more,
frequency is displayed in 0.1 increments. Therefore,
the minimum varying width is 0.1 even when [Pr. 295
<0.1].
When the set frequency (speed) is 1000 or more,
frequency is displayed in 1 increments. Therefore,
the minimum varying width is 1 even when [Pr.
295<1].
(5) Buzzer control [Pr. 990]
You can select to make the buzzer "beep" when you
press key of the operation panel and parameter unit
(FR-PU04/FR-PU07) or not by using [Pr. 990].
2.18.8 Setting an operation panel (PA02) for FR-E500 series
Operation panel for the FR-E500 series (PA02) can be used by connecting with PU cable.
(PA02 cannot be connected to the inverter body directly.)

(1) Built-in potentiometer switching [Pr. 146]
Switches the frequency setting method between the
PA02 built-in frequency setting potentiometer and
digital frequency setting by the
Set [Pr.146 =0] only when operating by a built-in
frequency setting potentiometer of an operation
panel for the FR-500 series (PA02). When [Pr.146
=0], operation may not be available from an inverter's
operation panel or by communication.
(2) Bias and gain of the built-in frequency
setting potentiometer [C22 (Pr. 922) to C25

(6) PU contrast adjustment [Pr. 991]
The LCD contrast of the parameter unit (FR-PU04/
FR-PU07) can be adjusted using [Pr. 991].
Decreasing the setting value makes contrast light.
The contrast can be adjusted by changing the setting
