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