General Mach Discussion / siemens analog signal question

« on: March 23, 2008, 04:20:25 PM »

Does anybody know what the (VDI) standard is. I'm still trying to start a plan to upgrade my simodrive.I have found out its a +- 10 volt speed command. conforming to VDI  I need to know if i'm going to run into some wierd incompatibility  Thanks Al

How about a research topic .As a group there are many thousands of hours spent  surfing for information .If anyone finds a site with good information they could post it.This could save members a lot of time.Heres a start  www.legacypower.net/documents    AL

General Mach Discussion / Re: six phase stepper reprogram?

« on: March 22, 2008, 10:39:46 AM »

Thank you for your reply.What i am trying to do is this.I have a old 610 simodrive with a good DC bus and three phase AC  inverters.I would like to lose the ancient control and drive the inverters directly.This takes a six switch bridge driver.Or six interleaved pwm signals.I did find DSPIC board at www.futurlec.com that would do it with commutation.But its far above my skills to write the code.Currently the project is scouring the pic freeware but no prize yet.Thank you for any input Al

ancient pc stuff  windows generally does not like different drivers for the same type of devices. try generic drivers.also avoid the first pci slot it is designed more for a disk drive and cause conflicts with some devices.It doesnt cost anything to try  Al

General Mach Discussion / six phase stepper reprogram?

« on: March 16, 2008, 05:20:03 PM »

Is it possible to use the signal  for a six wire stepper to drive a six switch inverter bridge? this would solve my salvage the simodrive problem.I am also thinking of the small pic boards for robotic hobbyists.But I couldnt program one. Any input thanks Al

Good Idea but It only goes back to the 611 series mine is a 610. I did talk to siemens about this one and they believed it cold be done with some additional dac's. But there policy of no information and relying on closers.turned me pretty cold.I did find the pinout for the inverters,but it looks like they require a pwm for each phase (ac servos)So I'll have hack it somewhere else.The bookshelf Idea Is also good but the rest of the machine hard wire is in there.I just had a brain flash.I am thinking of useing small drives as a preamp to get the three pulses if I can find one that outputs pwm. thankyou I am open to any suggestions Al

Hello Iam new to this but I have a project.It is a acroloc vmc with the above controller.What I would like to do control the inverter section directly and and get rid of some old and propriatory electronics.I know the inverters take a pwm signal.My problem is the interface is a 16 pin two row connecter and I dont have a clue which pin is what.the siemens website has zip.does anyone have any info on this . or is there a way to identify pin function thankyou AL

I  have been reading as a guest for some time.And I still do not know if machx can now do modulation or is it setable for tuneing. thanks al
