Frequency Setting Voltage (Current) Bias And Gain - Mitsubishi Electric FR-F820-00046 Instruction Manual

5.9.5

Frequency setting voltage (current) bias and gain

The magnitude (slope) of the output frequency can be set as desired in relation to the frequency setting signal (0 to 5 VDC, 0
to 10 VDC, or 4 to 20 mA). Use Pr.73 Analog input selection (Pr.267 Terminal 4 input selection) and the voltage/current
input selection switch to switch among input of 0 to 5 VDC, 0 to 10 V, and 4 to 20 mA. (Refer to
