Frequency Setting By Analog Input (Terminal 2, 4) - Mitsubishi Electric FR-D720S SC EC Instruction Manual

Parameter
6.15

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 (cur-
rent)
6.15.1 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.
The following settings are possible:
● Select reference voltages and currents: 0–10V, 0–5V oder 0/4–20mA
● Suppress motor reversing
