Hi Jon I think you are the guy that adds output filters to all his drives. As you are well aware many of these don't have any filters. Being the experienced...

That is what I did with some Yaskawa disc motors a while back. ISTR I needed something like 1mH to get the current down to a reasonable value. Apart from their...
I have some disk servo motors and was thinking about adding inductors so that they can be used with Gecko's. One type of inductor that I was considering is a...
I would recommend that for efficiency reasons, if nothing else, that you instead consider purchasing (or otherwise obtaining) an iron powder, or a ferrite...

... If the inductance is high enough that the ripple current is low, then the iron shouldn't get a lot of hysteresis loss. But, a filament transformer is set...
Hi Jon It's not a problem to design a full filter to pull everything back to DC with minimal ripple. Many including me at present don't have any filtering at...

I highly recommend anyone within driving distance attend. Just don't steal any deals out from under my nose, I need to pick up quite a few things. And last...
Ron, I sneaked in directions to my friend Ernie off-list, since I spent 8 years in that area. It's about 65 miles from Baltimore Washington International (BWI)...
i have just read how the G203V microsteps in low rpms and morphs to single steps in higher rpms. 2 questions ... does the G201 do this, and does mach3 handle...
I believe the answer is yes to both. Even though the drives generate full step signals to the motors above a certain RPM, they always accept microstep inputs...
Peter [or anyone who know's the answer!], I know this is probably the wrong list to post this on, but thought I'd ask anyway.. How does a person decided which...
I received my Digi Speed-GX, ordered dc to dc just in the event I ever need it(saves me time). The jumper makes it selectable either way. I won't use it for...
Hi Jarrett, Oh, definitely with the DC-DC converter. :-) Seriously though, it depends on the equipment you plan to control with it. If you have a VFD that...

Thanks Peter [and Jim] I think I'll end up going Jim's route and getting the DC-DC setup, it's not going to hurt anything if I don't use it, and in the future...
