DSPIC SERVO DRIVER DOWNLOAD

The demand is 0 Tero Kontkanen is working on something like that, but as far as I know his project is not open-source. This project was developed as an inexpensive way to drive small dc brushed motors as positioning servos for use on a desktop sized CNC machine. Forgot to say the board runs fine. The new design uses 2 op-amps as an h-bridge. Since the low speed velocity estimation is very annoying. I have to match the component names and numbers with the schematic and make the power traces a bit wider.

I have to match the component names and numbers with the schematic dspif make the power traces a bit wider. This was not possible with a slower 18F part which takes uS to do the servo loop compared to 25uS on the 33FJ32gp This project was developed as an inexpensive way to drive small dc brushed motors as positioning servos for use on a desktop sized CNC machine.

The board is interfaced to the PC through 2 pins of a parallel port. Sedvo guess you will have the boards professionnaly manufactured, right?

July 26, at In other words I could dsoic the reccursion rate or how often I called the PID loop which improves the dynamics of positioning the actuator. Leave a Reply Cancel reply Your email address will not be published. August 11, at The power stage consists of a power op amp driven in constant current mode. I went along trying lots of different CN Pins to generate an external interrupt on change of state. Jitesh June 24, at Mike Super Member Total Posts: I set up a pin on a scope to toggle so the timer1 generates a square wave which I monitored with a scope.

I’ll try to dig out the jog-wheel HAL for you and post it here as a comment. This number can be up to 7 amps. Tronics Starting Member Total Posts: Good Luck, Mike Leave a Comment Click here to cancel reply.

And please include the references in it if possible. I think at some point I read that someone else was doing the exact same thing, but I lost track of it? Here, as if there’s not enough projects here to keep some of us busy.

July 6, at The picture might seem messy with a whole lot of wires – but I can assure you that it’s all very organized The optoisolators are now described at http: Ddspic sure about the rest: March 22, at Can you tell me more about seervo chokes you are using? July 9, at Dave, some notes, text, and a HAL file for my jogwheel now at: May 02, In: Hello I have attached a somewhat layout of the Lawrence Glaister dspic servo controller.

This makes frequency reading very stable because the timer 3 is triggered to start and then stop from CN23 change of state happening 6 times from the frequency entering the PIN from the sensor. August 12, at Results 25 to 36 of I will try to create cnc mill,I am not setisfied with stepmotion.

Sorry I do not have the code for this project available anymore.
