1:the function is valid
The function is applicable in the instance of low network voltage or heavy load for a
long time,inverter raises the output voltage with rising utilization rate of bus voltage.

When several motors drive the same load, each motor's load is different because of the
difference of motor's rated speed. The load of different motors can be balanced through
droop control function which makes the speed droop along with load increase.When the
motor outputs rated torque, actual frequency drop is equal to F8.24. User can adjust this
parameter from small to big gradually during commissioning. The relation between load
and output frequency is in the following figure:

This parameter adjustment speed droop of the frequency change-value of the
frequency inverter.
