Analog Input Selection (Pr. 73, Pr. 267) - Mitsubishi Electric FR-A720-0.4K Instruction Manual

Frequency/torque setting by analog
input (terminal 1, 2, 4)
REMARKS
⋅ When "4" is set in both Pr. 868 and Pr. 858, terminal 1 is made valid and terminal 4 has no function.
⋅ When "4" (stall prevention/torque limit) is set in Pr. 868, functions of terminal 4 become valid independently of whether the AU
terminal is on or off.

Pr. 807 Speed limit selection
Pr. 810 Torque limit input method selection

4.21.2 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 selection specifications, the override function and the input signal polarity.

(1) Selection of analog input specifications
⋅ For the terminals 1, 2, 4 used for analog input, voltage input (0 to 5V, 0 to 10V) or current input (4 to 20mA) can be
selected.
The current at terminal 2 and 4 is always 4 to 20mA when the voltage/current input switch is set to ON.
(A voltage/current input switch is provided for the 5.5K or more.)

CAUTION
When turning ON the voltage/current input switch, set input specifications of terminal to current input using Pr. 73 and Pr. 267.

Setting Range
You can select the input specifications of terminal
2 (0 to 5V, 0 to 10V, 4 to 20mA) and input
specifications of terminal 1 (0 to ±5V, 0 to ±10V).
For the 5.5K or more, the input specifications can
0 to 7, 10 to 17 be selected when the voltage/current input switch
is off. Terminal 2 is always used for current input
when the switch is on, the parameter needs to be
set to current input. Override and reversible
operation can be selected.

Description
For the 5.5K or more,
the input specifications
can be selected when
the voltage/current input
switch is off. Set "0"
when the switch is ON.
