Most big commercial drives have inbuilt circuitry to absorb that regenerative power, and trip themselves warning you if you go overvoltage, a common problem...
Hello, It sounds like the problem can only be related to the signaling from the printer port. Check if changing the polarity of the STEP signal in MACH3 has...
... overvoltage, a ... the DIY ... energy ... energy ... Tom C's, ... Our ESP series of Power Controllers that work with all Gecko drives have an embedded...
thanks for your post concerning my gecko drives. Could you please tell me more about the diodes you installed? I don't know what to even ask for when I go...
John, "I do this whenever my machine sits idle for more than a few minutes" - That is, in general, a very bad practice with ANY electronic device. Powering up...
Thanks Tom I knew you had gone to town on this in your power supplies, thought a mention was better than trying to remember all the features you put in to try...
It depends on what's blowing them, I covered most of that in my post, though reading back over your problem I haven't directly addressed your issue, or at...
John, I bet the diodes will fix one of your problem and it is an easy and cheap thing to try. I got diodes from Radio Shack. The one below would probably work...
I just got my G203V's and they work great with the large nema 23 motors that I have put in the CNC router that I am building. I am also putting together a...
John, Mark brings up the important point about the type of fuse you are using. He does not recommend putting the fuse between the DC power and the Gecko if I ...
You got the diodes the wrong way around Keith. The idea is that when the fuse is intact power flows from the DC supply to the gecko, but the gecko can also...
I agree, it's something in my system, and didn't mean to imply in any way that the gecko's were to blame. It's just weird how everything goes along fine then...
Mark, Thanks! I think Mariss shows placement of fuses in his "white paper", which I can't find, between the DC output and the Gecko but I may be wrong and it...
John, How do you have the switch for the AC wired? I use a relay on the breakout board that connects to a solid state relay. I use the DC side of the relay...
I think he does. At first look it seems a good idea. You start to get thinking when you don't see them on commercial kit, although there are a lot of...
... Excellent post sir! One minor addition. It's fuses (and breakers) are rated over certain ambient temperature ranges; too hot and the rating drops, too cold...
Hello everyone, I was wondering while reading the quick faq documents on the g540, more specificaly about the VFD pinouts. Are they used to power the g540? I...
The VFD pinouts are control outputs to the variable frequency drive if you have one for instance on your spindle. I can't get the doc for the g540 from the ...
Thanks It actually amazing how wild the characteristics can be on a simple fuse that we all trust so well. As for sizing breakers that's a whole new subject...
One more thought on this. I had same problem. Lots of looking around and I found a note by Mariss on CNCZone about placing a 47K ohm resistor between pins 1...
Hi, When I run my Emco F1 CNC near 14 ipm it complains to the point of stalling. I'm using 203V's. The Y axis seems to be the worst. I think this may be a...
Bob, It might be a problem with grounding or isolation from the PC due the absence of a breakout board. Sounds frustrating. Do you have the recommended star...
Keith, Thanks for the quick reply. I do have sheilded cables, one and only one end grounded. I'm not sure I have a star ground config I will double check that...
