 Parameter
A frequency command is given by input from the terminal block.
The inverter has three kinds of external analog input terminals.
For each input, relation between the input signal and the frequency command can be set inde-
pendently.
To add/subtract a command, the sub frequency input source selection, 1st-motor [AA102] and Calcula-
tion symbol selection for Speed reference, 1st-motor [AA105] should also be set. [Ai3] can be added to
[Ai1] and [Ai2] without choosing an operator in the [Cb-22][Ai3] terminal selection. For details, see
8-10-5 Analog Input on page 8-163.
Precautions for Correct Use
• The output of the inverter requires not only a frequency command but also an operation com-
mand.
• Note that the voltage input and the current input are switched from each other by the terminal
block switch.
• For adjustment of the analog input, see 8-10 Input Terminal Function on page 8-154.
