The Frequency Control Method attribute identifies the control method
associated with the axis.
The Basic Volts/Hertz control method applies voltage to the motor generally in
direct proportion to the commanded frequency or speed.
Sensorless Vector enhances the Basic Volts/Hertz algorithm by utilizing current
vectors Iq and Id for superior control at low speeds.
Fan/Pump Volts/Hertz is based on the Basic Volts/Hertz but is specifically
tailored for fan/pump applications.
Sensorless Vector Economy applies the Sensorless vector algorithm but seeks to
reduce energy consumption when the applied load is less than 50% of rating.
