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 dy-
namic 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.
