BIAS/GAIN FUNCTION SELECT, BIAS FREQUENCY,
GAIN FREQUENCY (Parameter P55, P56 and P57)
The relation with the output frequency and frequency setting signal (panel potentiometer,
external potentiometer, 0 to 5V, 0 to 10V, 4 to 20mA), can be changed randomly. Use this
function according to the application.

∗
(When "000" is set, 0V stop will function.)
Note 1)
A frequency exceeding the maximum output frequency or upper frequency clamp
cannot be output.
The frequency will not drop below the lower frequency clamp.
Note 2)
Even if a minus frequency setting signal is input, the inverter will not run in reverse.
