8.3.2.5 Digital Input
When using the digital signal at the DI port of the Logger1000 as the dispatching input, set
the Reactive Control Mode to Digital input.
Step 1 Click “Power control→Reactive power” to enter the reactive power interface.
Step 2 Set the Reactive Control Mode to Digital input.
Step 3 Set DI control parameters. For specific parameter description, refer to the following table.
table 8-10 Parameter description

Description
Control Method
Open-loop control: Reactive instruction controlled by DI is
sent to power output port of the inverter, thereby achieving
active power control.
Closed-loop control: Reactive instruction controlled by DI
is used as target value and reactive power and power factor
of the meter need to be collected and used as input parame-
ters, 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 prop-
erty boundary point.

Control Cycle
Time interval of delivering dispatching instructions
Parameter range: 5~60s
Instruction Type
PF: set the power factor as the target value
%: set reactive power percentage
Note: *Only when the Control Method is set to Closed-loop control, the parameter Select
energy meter/transformer is settable.
The open-loop control has the PF Instruction Type, and the closed-loop control
has the PF Instruction Type only when the meter is selected.
Step 4 Add digital input manner
Select the desired DI channel, fill in the Percentage (PF), and click Save.
