Analog Output Operation

In inverter applications it is useful to monitor the
inverter operation from a remote location or from the
front panel of an inverter enclosure. In some cases,
this requires only a panel-mounted volt meter. In other
cases, a controller such as a PLC may provide the
inverter's frequency command, and require inverter
feedback data (such as output frequency or output
current) to confirm actual operation. The analog output
terminal [AM] serves these purposes.
The inverter provides an analog voltage output on terminal [AM] with terminal [L] as analog
GND reference. The [AM] can output inverter frequency or current output value. Note that
the voltage range is 0 to +10V (positive-going only), regardless of forward or reverse motor
