Bob, When a servo acts erratic like that it's usually the motor leads "talking" to the encoder cable. It will wreak havoc with loop. Just running smoothly...
The new ones have a problem and from what I remember, if you put a ~.1uF cap at the power pins of the heds, it will work! Have a friend up in TN that did this...
I've just tried a G320 running a 36 volt, 18 amp servo but it seems to be limited to 4.5 amps. I couldn't understand why the axis was running so slowly so I...
Glen, If u want to see the current go up when connected to gecko, try to turn the motor shaft. when the servo motor is locked with gecko, it just draws current...
Forgot to mention, I tried to turn the ballscrew by hand but the motor was too strong @ less than the 4.5 amps when driving the axis. I may be able to use a...
First, since you are using an external 5 VDC for the encoder did you put the 470 ohm resistor from enc+ to enc-? Next did you connect the external PS ground to...
We've used loads of HEDs encoders on all sorts of projects, but as the lead length gets longer the errors start to creep in so as Marriss and Dan have ...
Hi Mark, ... other line driver usually so we have differential line output and then it will run the signal over tens of meters of cable without issue, if we...
Hi Mark, Will you please offer some more details on suitable decoder chips. I purchased several AMT encoders and AMT line drivers, and want to connect to a...
Not got my notes with me, but the series I commonly use I think are the Maxim 487 chips and a few others I don’t remember. Do a web search for maxim 487, and...
Well, that's a good sign that gecko is a very effective in conserving power when in idle position. So, for 16 amps motor, you still got 11.5 amps reserve in...
I'm fixin' to wire my HobbyCNC 305 oz-in motors to one of Jeff's Soigeneris boxes. I got the connections from this thread and will go that route: Color...
Hi Wonder if anyone can explain how the encoder lines per turn are set in a Gecko G320 drive. If one was to set up 2 idential DC servo motors but with 2...
The G320 doesn't know, or care, what the encoder line count is. But if you put a 500 line encoder on one motor, and a 1000 line encoder on another, and expect...
I have blown a G203v by switching the DC power on and off to the drive. I know..... I shouldn't do that! Anyway, I cooked a resistor on the board with...
Greeting all: I'm hoping somebody can advise as to an odd problem I'm having with a 203V. I hooked it up to mach using a 2nd port, I tested the wiring using an...
Kristin, did you get your motors running? I asked over on the HobbyCNC forum and got the spec sheet for the 305 oz-in motors from Dave. Jack's "diagram" is...
I just found all the spec sheets for the HobbyCNC motors. Their color codes are all the same! The 205 oz-in motors are rated for 2.8 A/phase in parallel....
Hello all, I have CandCNC UBOB,Quad-PS,and the MTA100 Cable Interface Card, and cables that i have never used. Thinking of going another route for my...
Hi group! I just bought a G320X to try it out. I've been working some with steppers but I'm new to servos. I've set it up according to the manual and worked my...
Hi Mariss - Are you having a Customer Appreciation Sale this year?? The G320X looks like a good candidate for me after running with G340's for the last 7...
The encoder count difference is not accounted for in the G320. That will be handled by the step generator. If you are using something like Mach software for...
