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 increasing.
When the motor outputs rated torque, actual frequency drop is equal to P8.28. User can
adjust this parameter from small to big gradually during commissioning. The relation
between load and output frequency is in the following figure.
