Hi all, I have a 3 axis machine with servo motors controlled by G320s. The G320 are about 2 years old. The encoders have 400 increments. This all runs fine...
... Hi Les, ... Done so. The problem persists... ... The problem is the encoder wiring. I made a short replacement cable and tried with it. The error is gone. ...
Hi I have a bit of info on the noise issue and what I did at my website: http://www.woodsolutions.com/diy-electronics.htm The info is near the bottom of the...
... Hi Mariss, ... Opps, unfortunately it is a HEDS-9100. Now what can I do about this? Replacing the encoders or is there a solution? Hoping for an easy...
... I have some QEDS-9587 heads in here. Can I simply replace the head without changing the wiring? And can I use the 400 increment discs with this head? The...
... Is the encoder a US Digital product? If so, the internal capacitance to stabilize the power in the encoder is VERY weak. Applying at least a 0.1 uF cap...
... Hi Jon, ... Yes indeed, US Digital, in a black housing. Ok, that sounds promising. Sorry for beeing dense, but which kind of cap? An electrolyt? You say at...
... Hi Mariss - I get the yellow LED when the motors **are** attached. When I first power up, the G203V have both there yellow and green lights on. As soon as...

I run a G540 with four steppers (see http://www.kelinginc.net/KL23H2100-35-4B.pdf for specs). Using 3,48Kohm resistors. Having tried both Mach3 and even EMC2...
Yes, you can fix the encoder. Unbelievably the HEDS-9100 has no power supply bypass capacitor. Bypass capacitors are mandatory in every electronics circuit yet...
I would first suspect a configuration problem. I take it you have the A axis slaved to X? Jeff Birt Check out - Soigeneris.com From: geckodrive@yahoogroups.com...
... It probably doesn't matter. ... Anything between 0.1 uF and 10 uF should be fine. ... Yes, if using an electrolytic, the minus of the cap goes to the minus...
The red LED is on as well. There is no switching activity during power-on reset time (red LED) so the yellow LED will be on for 1 second. I can change the code...
Jon, Electrolytic caps are NOT recommended. Their internal inductance and series resistance makes them useless for high-frequency supply bypass. Use MLCC...
... Oh, agreed, that would be the best choice for the application, but some people may not have them in their junk box. Actually, I think a small electrolytic...
... Since I neither have elcos nor ceramic caps I'll have to go to the store anyway. ... No leads? I'm sure there will be leads, otherwise it's sand ;-) ...
The HEDS-9100 is a clamshell design. The LED circuit is on the top half, the detectors are on the bottom. Both halves need +5V, GND so the loops bridge the...
... Those "loops" jump the power over to the LED side of the encoder module, and are connected directly to the power and ground pins. Just a convenient place...
... I just hung up from speaking with you about this problem, and was delighted by the information you shared with me concerning the design of my machine. I...
Running a couple of smaller NEMA23 47V DC servo motors with G320 controllers. Linear PS is putting out a confirmed clean 36VDC. After running fine for about 1...
Re: Position error G320 Hi Mariss, in the beginning I had problems to reproduce the error without a capacitor. Therefore it took a bit longer to make the error...
What style of caps are they( ceramic or electrolytic) ? Where they new a year ago or were they older stock? What are their ratings? What condition are your...
As far as I know you should not use capacitors on a switching drive like the G320. You will get very high currents flowing through the caps due to the...
Charles - Is it possible you could post a picture of the cap in place? I don't understand where you soldered the cap onto. I am losing steps myself after...
