Frequency setting by analog input (terminal 2, 4)

4.17 Frequency setting by analog input (terminal 2, 4)
Purpose
Selection of voltage/current input
(terminal 2, 4)
Perform forward/reverse rotation by
analog input.
Adjustment (calibration) of analog
input frequency and voltage (current)

4.17.1 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 specifications and input signal.

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.
Either 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 to change Pr. 267 and voltage/current input switch.
Rated specifications of terminal 4 change according to the voltage/current input switch setting.
Voltage input: Input resistance 10kΩ
Current input: Input resistance 233Ω
