Load drooping “LoadDrooping”
The drooping function enables speed drop as a function of load.
This parameter sets the value corresponding to the nominal torque of
the motor.
Torque [%]
100 %
Reference
Actual
Speed [rpm]
10 %
Example:
If load drooping is set to 10 % for a motor that has a nominal frequency
of 50 Hz and is nominally loaded (100 % of torque) the output frequency is allowed
to decrease 5 Hz from the frequency reference. The function is used for e.g. when
balanced load is needed for mechanically connected motors.
