Frequency/torque setting by analog input (terminals 1, 2 and 4)
Perform operation by analog input current
When the pressure or temperature is controlled constant by a fan, pump, etc., automatic oper-
ation can be performed by inputting the output signal 0/4 to 20mA of the adjuster to across the
terminals 4-5.
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.
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.
