Mitsubishi Electric FR-A820-00046 Instruction Manual page 611

Parameters
To run with an analog input voltage
● Concerning the frequency setting signal, input 0 to 5 V DC (or 0 to 10 V DC) to terminals 2 and 5.
The 5 V (10 V) input is the maximum output frequency.
● The power supply 5 V (10 V) can be input by either using the internal power supply or preparing
an external power supply. The internal power source is 5 V DC output between terminals 10 and
5, and 10 V DC output between terminals 10E and 5.
Tab. 5-155: Built-in power supply voltage
input selection
● To supply the 10 V DC input to terminal 2, set "0, 2, 4, 10, 12, or 14" in Pr. 73. (The initial value is 0
to 5 V.)
● Setting "1 (0 to 5 V DC)" or "2 (0 to 10 V DC)" in Pr. 267 and turning the voltage/current input
switches OFF sets the terminal 4 to the voltage input specification. Turning ON the AU signal
activates terminal 4 input.
NOTE The wiring length of the terminal 10, 2, 5 should be 30 m at maximum.
