Typically, dancers are employed on winders or some sort of web line to maintain the proper speed or tension. The PID block, along with the C200, C300, M400, M600, M700, and M750 drives, incorporates a feed forward on the output side of the PID block. Often, I utilize this feed forward as the line speed, and have the dancer connected to the PID to trim the final speed command. See parameter 14.002. This would be mapped to whatever parameter has the line speed. Parameter 14.016 would be mapped to parameter 1.021 and you would then tell the drive to use preset 1. Alternatively, you could simply utilize the trimming offset parameter 1.004 and have the PID output control parameter 1.004 instead of using the feed forward on the PID block. You would then map 14.016 to 1.004. Then you would use a analog input or a preset speed for the line speed. Another option would be to have the dancer connected to the PID blog but then have the output of the dancer control parameter 3.022. The nice thing about doing it this way is that the dancer doesn't have to go through the acceleration and deceleration ramps. This allows the PID to have quicker response times to any sudden changes, however you might need to implement some sort of centering routine when you first web up the line. I would Recommend looking at the block diagrams to understand what I’m referring to. Please note that if you have an M600 and up there are more options. The line speed could follower an encoder. As I don’t know what drive you are looking to use, I’m limited in how I can respond. If you still need help let me know I'll try to help where I can.
@@vfdcode thank you so much for this info, im currently studying and learning these drives, Do you any worked examples/applications, i could possibly learn, highly appreciated🙏
I would love to learn more about these vsds, such has applications, do you have an email add, that i can send through questions when im learning these, you have such great content, i was watching all of your videos, they so understanding
Can you create some content on the control techniques vfds, like how you setup the encoder module, I/O module application module?
Can you make a video, to show how you monitor the PID on CT-SCOPE
How would you do the dancer application using pid?

Im currently learning the c200 & m400 at the moment, thereafter i would like to move on
I did do a pump system with pid, but very basic application
