    Figure 1: Even general-purpose VFDs, like the Automation Direct DURApulse GS20 family, include advanced features like sensorless vector control and torque control modes. More capable models, like the WEG CFW500, include these capabilities, and add other features, like encoder support and flux vector control mode which allows 100% torque at zero speed.
