4.2.82 AM and AMI terminals
You can monitor the inverter output frequency and output current via the AM and
AMI terminals on the control circuit block.
The AM terminal outputs an analog voltage signal (0 to 10 V).
The AMI terminal outputs an analog current signal (4 to 20 mA).
The early precision is +-20%. Please adjust it as needed.
(1) AM siginal selection /AMI signal selection
Select the signals to be output from the AM and AMI terminals among those shown below.

[AMI] siginal
selection
*1 This signal is output only when the V/F characteristic curve selection
(see Section 4.2.18) is the sensorless vector control, 0Hz-range
sensorless vector control, or vector control with sensor.
*2 The voltage range is 0 to +10V(positive-going only),regardless of
forward or reverse moter rotation. In addition, please do offset
adjustment when this outputs negative-going of the output torque (signed).
*3 The actually detected output frequency is output when the V/F
characteristic curve selection is the vector control with sensor (A044 = 05).
*4
For detail of the function, refer "Programing software EZ-SQ user manual".
(2) AM/AMI adjustment
The early precision is +-20%. Please adjust it as needed.
Adjust the inverter output gain for the external meters connected to the AM and AMI terminals.

AMI offset adjustment
*1 When the current range of AMI terminal output is 4 to 20 mA, the offset of 4 mA is approximately 20%.
The adjustment is the following procedure. (In the case of AMI, it is similar)
a.
In a state of C028=00, and please run moter at the maximum frequency.
b. Adjust offset C109 first, and then use C106 to set the voltage for full scale output.
