PARAMETER
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 ].
(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
with of the parameter unit.
At this time, press to store the setting.
2.18.8 Setting an operation panel (PA02) for FR-E500 series
(E700)(D700)
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 key.
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
(Pr. 923)]
When the operation panel (PA02) for the FR-E500
series is hooked up with the PU cable, the magnitude
(slope) of the output frequency to the frequency
setting potentiometer of the operation panel can be
set as desired.
Adjust the bias of the potentiometer of the operation
panel using [
Pr. 922 (C22, C23)] and gain with [ Pr. 923
(C24, C25)].
