High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
• The digital terminal AM/AMI on the control circuit terminal block enables the monitoring of the output
frequency and the output current.
The terminal AM provides an analog output of 0 to 10 V.
The terminal AMI provides an analog output of 0 to 20 mA. By default, this terminal is set to provide
an analog output of 4 to 20 mA.
Select the signal you want to output from the following table.

Output frequency
*1
*1. 00 (Output frequency) represents a frequency value that takes into account the aspects of vector control
compensation (such as sensorless vector control) and even stabilization control.
07 (LAD frequency) represents the frequency commanded by the inverter and is equivalent of the Output
Frequency Monitor (d001) value.
0 to Maximum frequency (Hz)

Output torque
*3
*3. This signal will be output only when Sensorless vector control, 0-Hz sensorless vector control, or Sensor vector
control is selected in Control Method (V/f Characteristics) on page 7-34.
*4. The specifications of the output torque (signed) are as follows.
In the above example,
· When AM Gain Setting (C106) = 100%, AM output = 10 V at torque output of 100%, and
· When AM Gain Setting (C106) = 50%, AM output = 7.5 V at torque output of 100%.
