If you are working on an application that requires accurate velocity control with a wide or continuously variable range of possible speeds, watch this video to learn about ClearPath, the all-in-one brushless servo system used in "Follow Digital Velocity Command". To use this mode, you supply a frequency of PWM command signal that is proportional to your desired speed.

To use this mode, you supply a frequency or PWM signal (bipolar or unipolar) that is proportional to your desired speed. These digital signals are more noise immune than analog command signals. To send these commands, you can use a PLC, function generator, or other frequency/PWM source. To learn the differences between bipolar and unipolar PWM as well as frequency, take a look at this video.
The acceleration and deceleration rates are determined by how fast you change the command signal. ClearPath's MSP (Motor Setup Program) software allows you to set acceleration and deceleration limits for increased safety in your application. You also set a RAS (Teknic's feature that limits the jerk and jerk derivative) value to smooth the transitions between different speeds without using complex software.
