Speed Setting By Analog Input (Terminal 2, 4); Analog Input Selection (Pr.73, Pr.267) - Mitsubishi Electric FR-E700EX Instruction Manual

Speed setting by analog input (terminal 2, 4)

4.15 Speed setting by analog input (terminal 2, 4)

Purpose
To select voltage/current input
(terminal 2, 4)
To perform forward/reverse rotation
by analog input
To adjust (calibrate) analog input
speed and voltage (current)

4.15.1 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 specifications and input signal.

selection
The above parameters can be set when Pr.160 Extended function display selection = "0". (Refer to page 182)
(1) 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.
