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 C028 to configure terminal [AM] as indicated below.

	00	Inverter output frequency
	01	Inverter output current
	02	Inverter output torque
	03	Digital output freqnency
	04	Inverter output goltage
	05	Inverter input power
C028	06	Electronic Thermal Load
	07	LAD frequency
	08	Digital current monitor
	10	Cooling fin temperature
	12	General purpose
