(2) Perform operation by analog input voltage
⋅ The frequency setting signal inputs 0 to 5VDC (or 0 to 10VDC) to across
the terminals 2 and 5. The 5V (10V) input is the maximum output
frequency. The maximum output frequency is reached when 5V (10V) is
2
input.
⋅ The power supply 5V (10V) can be input by either using the internal
power supply or preparing an external power supply. The internal power
supply outputs 5VDC across terminals 10 and 5, or 10V across terminals
10E and 5.

⋅ When inputting 10VDC to the terminal 2, set any of "0, 2, 4, 10, 12, 14"
in Pr. 73. (The initial value is 0 to 5V)
⋅ Setting "1 (0 to 5VDC)" or "2 (0 to 10VDC)" in Pr. 267 and a voltage/
current input switch in the OFF position changes the terminal 4 to the
voltage input specification. When the AU signal turns ON, the terminal 4
input becomes valid.

⋅ The AU signal must be turned ON to use the terminal 4.
⋅ Setting any of "6, 7, 16, 17" in Pr. 73 and a voltage/current input switch in
