FR-E500 series operation panel (PA02) setting
4.24.2 Bias and gain of the built-in frequency setting potentiometer (C22 (Pr. 922) to C25
(Pr. 923))
Adjust the bias of the potentiometer of the operation panel
using
Pr. 922 (C22, C23) and gain with Pr. 923 (C24, C25) .
<Setting>
[Setting from the FR-E500 series operation panel (PA02)]
Bias/gain adjustment methods using the built-in potentiometer are shown below.
Method to adjust any point by turning the potentiometer.
Method to adjust any point without turning the potentiometer.
Method to adjust the bias/gain frequency only.
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.
