Frequency setting by analog input (terminal 2, 4)
Parameter
6 - 148
Selection of analog input specifications
For the terminal 2 for analog voltage input, 0 to 5V (initial value) or 0 to 10V can be selected. Ei-
ther voltage input (0 to 5V, 0 to 10V) or current input (4 to 20mA initial value) can be selected for
terminal 4 used for analog input. Change the input specifications by setting Pr. 73 and Pr. 267
and voltage/current input switch.
Rated specifications of terminal 4 change according to thevoltage/current input switch setting:
Voltage input: Input resistance 10k

CAUTION:
Set Pr. 267 and a voltage/current input switch correctly, then input an analog signal
in accordance with the setting. Incorrect setting as in the table below could cause
component damage. Incorrect settings other than below can cause abnormal opera-
tion.

(electrical load in the analog signal output circuit of
signal output devices increases)

This could cause component damage of the inverter
signal input circuit.
(output power in the analog signal output circuit of sig-
nal output devices increases)
