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 rotation. Use
