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.
