P3.1.2.7 LOAD DROOPING
The drooping function enables speed drop as a function of load. This parameter sets that
amount corresponding to the nominal torque of the motor.
This function is used e.g. when balanced load is needed for mechanically connected motors or
dynamic speed drooping is needed because of changing load.
E.g. if load drooping is set to 10% for a motor with a nominal frequency of 50 Hz and the motor
is loaded with nominal load (100 % of torque) the output frequency is allowed to decrease 5 Hz
from the frequency reference.
