10.2.2.4 AI Control
When using the analog signal at the AI port of the Logger3000 as the dispatching input,
set the reactive control mode to "Analog input".
step 1 Click "Power control" -> "Reactive power" to enter the reactive power interface.
step 2 Set the reactive control mode to "Analog input".
step 3 Set AI control parameters. For specific parameter description, refer to the following

Communication is abnormal, and specified dispatch output
value is delivered.
Open loop control: Reactive instruction controlled by AI is sent
to power output port of the inverter, thereby achieving active
power control.
Closed-loop control: Reactive instruction controlled by AI is
used as target value and reactive power and power factor of
the meter need to be collected and used as input parameters,
and reactive power compensation ratio is calculated and sent
to power output port of the inverter. Generally, this strategy is
used for improving the power factor of the property boundary
point.
