[AM] and [AMI]
Terminals
The [AM] and [AMI] terminals provide signals
to monitor various inverter parameters such as
output frequency, output current, and output
voltage. 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. Six 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].
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.
