Frequency setting by analog input (terminal 1, 2, 4)
(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
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 changes the
terminal 4 to the voltage input specification. When the AU signal turns
ON, the terminal 4 input becomes valid.
(3) Perform operation by analog input current
 When the pressure or temperature is controlled constant by a fan, pump,
etc., automatic operation can be performed by inputting the output signal
4 to 20mADC of the adjuster to across the terminals 4 and 5.
 The AU signal must be turned ON to use the terminal 4.
 Setting any of "6, 7, 16, 17" in Pr. 73 changes the terminal 2 to the
current input specification. At this time, the AU signal need not be turned
ON.
