You can monitor the inverter output frequency and output current via the AM
and AMI terminals on the control circuit block.
The AMI terminal outputs an analog current signal (4 to 20 mA).
(1) AM siginal selection /AMI signal selection
Select the signals to be output from the AM and AMI terminals among those shown below.

*3 The actually detected output frequency is output when the V/F characteristic curve selection is the
vector control with sensor (A044 = 05).

(2) AM/AMI adjustment
Adjust the inverter output gain for the external meters connected to the AM and AMI terminals.
Item Function code Range of data Description
Setting of the gain for AM monitoring C106 50. to 200. (%) Setting of the gain for AM monitoring
Setting of the offset for AM monitoring C109 0 to 100 (%) Setting of the offset for AM monitoring
Setting of the gain for AMI monitoring C107 50. to 200. (%) Setting of the gain for AMI monitoring
Setting of the offset for AMI monitoring C110 0 to 100 (%) Setting of the offset for AMI monitoring
Note: The offset data is in percentage (%).
(Example) When the current range of AMI terminal output is 4 to 20 mA (default), the offset of 4 mA
is 20%.
