1） In case no energy meter is selected, at the beginning
time, the active instruction configured locally is used
as target value, and active power compensation ratio
is calculated and sent to the power output port of
the inverter. Generally, this strategy is used for fast
and accurate active power regulation.
2） In case an energy meter is selected, at the beginning
time, active instruction configured locally is used as
target value, active power of the meter needs to be
collected and used as input parameter, and active
power compensation ratio is calculated and sent to
the power output port of the inverter. Generally, this
strategy is used for anti-backflow or avoiding zero

Time interval of delivering dispatching instructions
Parameter range: 5~60s
Q-Method
kW: set active power value
%: set active power percentage
Note: *Only when the control method is set to "Closed-loop control", the parameter
"Select energy meter" is settable.
Step 4 Add local power control manner
Fill in "Start time" and "Percentage" (fixed value of active power), and click "Save".
Subsequent operation
Delete local power control manner: select a local control manner that needs to be
deleted, and click "Clear data".
AI control
When using the analog signal at the AI port of the Logger1000 as the dispatching
input, set the active control mode to "Analog input".
Step 1 Click "Power control" -> "Active power" to enter the active power interface.
Step 2 Set the active control mode to "Analog input".
Step 3 Set AI control parameters. For specific parameter description, refer to the
