· In closed loop control, the drive uses the encoder feedback in its control algorithm to know exactly what to output to the motor to run at the desired speed and torque. First, motor information goes through the encoder evaluation. One example of an encoder adjustment is if the encoder is placed on the output of a gearbox instead of on the motor

· The VFD (variable frequency drive) is a type of motor control that converts direct current (dc) into variable-frequency alternating current (ac). These VFD's not only convert the power, but also boost and regulate it before sending it to the ac motor. The VFD does this by varying the field on the stator and rotating its angle.
