... When I looked at the posted pics, I thought we'd maybe call this one the "stick"... Especially with all those wires branching out from both sides<G> ...
... <snip>dont go thinking they are "TTL inputs" .. ... Robin, Excellent point and post. Small addition... I think adding "Greater than 5" makes this statement...
... Lance, you've hit the nail on the head! (That the G200x was headed far beyond the "CNC" market--into the MUCH larger "motion control" market--was apparent...
Hello, If you have an AC spindle motor consider the GS2 or Durapulse drives from automationdirect.com. I've got a GS2 drive myself. They both accept 0-10V...
Mariss; IEC-1131 defines five languages for PLC programming. Of these, LD (ladder diagram) and ST (structured text) are the most common. There is a company in...
Randy, Resolvers are not encoders. Do not try to use them as such. Resolvers must be excited by an outside AC signal and then the multiple sine waves are...
This is to announce the First Annual CNC-Workshop (How's that for optimism?) To be held June 20 through 26 in the Galesburg, Illinois area - Will include -...
... Not really. I mean, yes, the macro's in MAch4 will operate the g200x just like in MAch3 for the most part, but what I was thinking for the PLC side was a...
Hi Mariss FWIW, look at the Festo SPC200, www.festo.com this is a very capable controller with motion commands similar to G-codes and PLC functions written ...
... you ... Ladder logic is a pain to learn because of its similarities to assembler. Addressing is either octal or hex, and bit-wise manipulation of registers...
Ron, Ignorance on my part. I did not know the difference. Then what I have are encoders. The output is a digital pulse with a A and B phase. Now I know. ...
To all: Please straighten me out on the optoisolator and stepper drive. As I understand the circuit; +5 volts is applied to an LED that has a 1k resistor in...
Henrick, OK thank you for the information. John ... From: "Henrik Olsson" <henrik-olsson@...> To: <geckodrive@yahoogroups.com> Sent: Wednesday, March 02,...
Sorry to have been such a pain but hopefully I am on the way to making this work. I am using a 486 that I've had for years and that was working when replaced. ...
... When the Gecko first powers up its in a sort of stand-by state ... upon seeing the first pulse from the CPU, it wakes up and starts passing motor current....
The G201 / G210 drives don't have power-on reset. The drive uses a 4- bit decade counter. The counter, being 4-bit, has 16 possible power- on states, of 6 are...
Mariss, Henrik and all others a big THANK YOU for straightening me out on the way the drivers work as well as my other problems. Hopefully you can see why I...
... Ah .. that explains why sometimes it comes up locked, sometimes not .. I always assumed it was reset to a "stand-by" state, and sometimes it must get a...
Ladder logic!! sends a chill up my spine, lol Back in 1989 I developed a natural english interface GUI for custom PLC hardware. The GUI guided you along with...
In the file section there is a folder labeled G201 and G210 Stepper Motor Drive Stuff. It contains four PDF files with Schematic Diagrams for over voltage ...
... I didn't see any files with servo as the name or description, but the circuits are to dump energy in the power supply. Read the 'RETURNED ENERGY.pdf' for...
... Thanks Dave, I appreciate your response. In the file dump1.pdf when you open it is titled "DC BRUSH TYPE SERVODRIVE E-STOP." Since it is in the Stepper ...
Hi! What changes it would take to modify a G320 for a higher voltage? It would be cool to run over 200Vdc motors directly from rectified 230Vac voltage...
... avoid ... Assume you have a mill, the rapids are not so great and the flywheel effect is not that great. Considder pretty much any screw driver will have...
It would take a lot: 1) The power section trace spacing is .0125" (.32mm). This is fine for 100V, not fine for 400V. 2) Bootstrap and bypass caps are 100VDC...
