Parameter
Perform operation by analog input voltage
The frequency setting signal inputs 0 to 5V DC (or 0 to 10V DC) to across the terminals 2-5.
The 5V (10V) input is the maximum output frequency. The maximum output frequency is
reached when 5V (10V) is 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 5V DC across terminals 10-5, or
10V across terminals 10E-5.

When inputting 10V DC 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 5V DC) or "2" (0 to 10V DC) in Pr. 267 changes the terminal 4 to the voltage
input specification. When the AU signal turns on, the terminal 4 input becomes valid.
NOTE The wiring length of the terminals 10, 2, and 5 should be 30m maximum.
