Am And Ami Terminals (C028, C029, C106, C108 To C110) - Hitachi L700 SERIES Instruction Manual

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).
(1) AM siginal selection /AMI signal selection
Select the signals to be output from the AM and AMI terminals among those shown below.

*1 This signal is output only when the V/F characteristic curve selection (see Section 4.2.17) is the
sensorless vector control.
*2 The specifications of the output torque (signed) are as follows:

*3 For detail of the function, refer "Programing software Ez-SQ user manual".
(2) AM/AMI adjustment
Adjust the inverter output gain for the external meters connected to the AM and AMI terminals.

Setting of the gain for AM monitoring
Setting of the offset for AM monitoring
Setting of the gain for AMI monitoring
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%.
