4.2.82 AM and AMI terminals<br />
You can monitor the inverter output frequency and output current via the AM<br />
and AMI terminals on the control circuit block.<br />
The AM terminal outputs an analog voltage signal (0 to 10 V).<br />
The AMI terminal outputs an analog current signal (4 to 20 mA).<br />

*1 This signal is output only when the V/F characteristic curve selection (see Section 4.2.18) is the<br />
sensorless vector control, 0Hz-range sensorless vector control, or vector control with sensor.<br />

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

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