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.
