When multiple drivers are driving the same one load, the speed difference will cause unbalance distribution of load,
which will result in too much load to the driver with higher speed. The droop control is to make speed troop changing
with the increase of the load, so as to equalizing load distribution. This parameter is to adjust frequency variation of
frequency drooping driver.
When F0.18=1 (high frequency mode), the upper limit of this parameter is 100.0Hz.

This function code is used for auto current amplitude limit during rotating speed tracking. When actual current arrives at
the threshold (FC.16), the driver will decrease frequency and limit current, then go on with tracking acceleration; the set
