(3) Perform operation by analog input current
Inverter
⋅ When the pressure or temperature is controlled constant by a fan, pump,
etc., automatic operation can be performed by inputting the output signal
Voltage/current
input switch 0 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 and a voltage/current input switch in
Inverter
the ON position changes the terminal 2 to the current input specification.

(4) Perform forward/reverse rotation by analog input
(polarity reversible operation)
⋅ Setting any of "10 to 17" in Pr. 73 enables polarity reversible operation.
⋅ Providing ± input (0 to ±5V or 0 to ±10V) to the terminal 1 enables
forward/reverse rotation operation according to the polarity.
