External analog input
This inverter has three kinds of external analog input terminals.
O-L terminal : 0 - 10Vdc OI-L termminal : 4 - 20mA
O2-L terminal : -10 / 0 / +10V
The setting contents of this function is as follows.

Assign 16(AT) to intelligent input terminal. The frequency setting is the values from terminals O, OI and O2
when 16(AT) isn’t assigned. The frequency set up when A006 is "00" becomes the value of O2. And, the
frequency set up when A006 is "01" or "02" becomes the value which OI and O2 were added to. The following
frequency command methods are available by combining A005, A006 with the intelligent input AT terminal.
In the case that reverse and FW(forward) terminals are ON, the inverter operates reversely when (main
frequency c auxiliarly frequency command)< 0.
