Droop control filtering

time
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 P1.41. User can adjust this
parameter from small to big gradually during commissioning.

This function is mostly used in textile and chemical industry and some application such as traversing and winding so
it is used for balancing the workload allocation when multiple motors are used to drive the same load. The output
frequency of the frequency inverters decreases as the load increases. You can reduce the workload of the motor
under load by decreasing the output frequency for this motor, implementing workload balancing among multiple
motors.P01.44 or P01.46=0,This function disable
