5-3 Speed Mode<br />
Speed Mode is necessary for applications that require precisely speed control, such as weaving, drilling<br />
and CNC type machines.Diagrams below shows the speed control system in two parts.<br />
First stage shows Speed processing and conditioning and the second stage shows the Speed controller<br />
With PI/P control modes, and controller1&2 selection and interface with torque control stage.<br />
