I have developed a brushed servomotor controller.
Maybe somebody is interested in it.
The inputs are step/direction signals.(you can use MACH2-3, KCAM4, etc.)
Maximum voltage: 90V
Maximum current: 20A
Selectable 2X and 4X quadrate encoder logic.
The main controller algorithm is a modified PID alg.
It has a PID controller manual and autotuning feature, full diagnostic via USB port and some other good features...
The price of the controller is hobby rated
If you are interested or have questions, write mail to: dubblecnc(at)gmail.com
Thanks for the replys and for the e-mails.
The price of 1 controller is 99USD.
The shipping cost is not included in the price!
We made an LPT port breakout board for our controller, you can connect maxium 4 servo controllers to it and all other LPT inputs and outputs can be accessed via it.
The price of the breakout board is 39USD.
Our website is only hungarian language, yet, but translation to english is in progress.
You can download the datasheet of the controller from here: http://dubble.extra.hu/hun/whale/seroconfig.zip There's an english documentation in the ZIP package( /DOC_ENG). You can tune the controller with our servoconfigurator program, which is in the package, also .
thats a nice looking layout you have.
the price is very good.
the software looks good as well.
this is not a home normal brew controller.
but it seems to be almost plug and play.
have seen the ghalil self tunning software?
o yeh, thanks for your advice on the pic forum,
Thanks for your appritiation.
Yes, I saw the Ghalil tuning software, but I think their controller are not hobby rated, the price is a "bit" higher.
Yes, it's easy to wire up the controllers and I think the RJ45 connectors are really good, because they're shielded and immune to industrial noise.
The first controller was tuneable via RS232, but COM ports are limited on a computer, so we changed it to USB(virtual serial port).
The package is natur aluminium, the bottom is 5mm wide, so it functions as a cooling rib.
Oh, I remember you from the Microchip forum, but now I have limited time to visit the forum Maybe I will take a look today.
I do not properly understand what have you asked about shipping. If you purchase a controller we send it to you in the aluminium pack as one of the above picture shows. The related programs and documentations you can download here for free:
http://dubble.extra.hu/hun/whale/seroconfig.zip There's an english documentation in the ZIP package( /DOC_ENG). You can find the controller description and the servoconfigurator program in the package, also . If you need, we can send an LPT port breakout board as well:
This board gets step/dir signals from the computer and distributes them between the controllers. Maximum 4 servo controllers can be attached to it with standard patch cables. The two connectors on the left are the unused inputs and outputs of the LPT port which can be also accessed. Moreover, this board can distribute digital supply, reset signal and stop signal too. If you connect the encoder to the controller properly, the controller will not make any failure! But if you don't, you can solve this problem with limitswitches.
