[AM] and [AMI]
Terminals
The [AM] and [AMI] terminals provide signals
to monitor various inverter parameters such as
output frequency, output current, and torque.
The terminals provide these analog signal types:
• [AM] terminal: 0–10V analog output signal
• [AMI] terminal: 4–20mA analog output
signal
These signals both use the [L] terminal for signal
return. Eight different inverter parameters may
be monitored independently at either the [AM]
or [AMI] terminal, as listed in the table below.
Use C028 to configure terminal [AM], and C029
to configure terminal [AMI].
Note 1: Display of torque is possible only during sensorless vector control, 0Hz domain
sensorless vector control, and vector control with feedback
The analog signals may need some adjustment for gain or offset to compensate for variances in
the system. For example, the signals may drive a panel meter and require a full-scale gain
adjustment. The table below lists the function codes and their descriptions. The [AM] and
[AMI] terminals have separate gain and offset adjustments. Note the default values.
