Frequency Setting By Analog Input (Terminal 1, 2, 4); Analog Input Selection (Pr. 73, Pr. 267) - Mitsubishi Electric FR-F740-00023-EC Instruction Manual

3.15 Frequency setting by analog input (terminal 1, 2, 4)

Purpose
Selection of voltage/current input
(terminal 1, 2, 4) Perform forward/
reverse rotation by analog input.
Adjust the main speed by analog
auxiliary input.
Noise elimination at the analog input
Adjustment (calibration) of analog
input frequency and voltage (current)

3.15.1 Analog input selection (Pr. 73, Pr. 267)

You can select the function that switches between forward rotation and reverse rotation according to the analog
input terminal selection specifications, the override function and the input signal polarity.
