6.20 Drooping control
f320 : Droop gain
f323 : Droop insensitive torque band
f324 : Droop output filter
Function
Drooping control has the function to prevent loads from concentrating at a specific motor because of
a load imbalance when multiple inverters are used to operate one machine.
These parameters are used to allow the motor to “slip” according to the load torque current. The
insensitive torque band and the gain can be adjusted using these parameters.
