I have my control box almost finished. I hooked up the servos on the bench (actually the kitchen table but we will not go there) and I can not get Z to work...
Runaway servo = no encoder connected to the Gecko. ... the bench (actually the kitchen table but we will not go there) and I can not get Z to work properly....
to go a little further, check your actual gecko connections...sometimes the insulation gets in the screw posts and the signals don't pass..... ... on ... and ...
Not the problem. As I have in the first post. I switched box amphenol connections with the Y axis and the problem followed the Z motor so the box to the...
curious george here... did you find the problem yet? ... amphenol connections with the Y axis and the problem followed the Z motor so the box to the Gecko is...
... Sounds to me like the PWM signals are cross-talking to the encoder inputs to the Gecko drive. I have found it critical to shield the encoder wires from the...
Mariss, Going through my instructions trying to find out why my Z servo motor runs away as soon as the Gecko is powered up I see where you say under "motor...
No, It's not a misprint, it got me too the first time. I don't know for sure, but I think the A and B encoder wires are relative to which way the motor spins....
Page 4/5 of the Gecko 320 paperwork says that you can hook up an external switch to reset the drive. My question is can I gang all three of the resets together...
I want to CNC a mill with 200+ lb. table/saddle weight. It has 5 turn per inch ballscrews, and I would like to use direct drive because of the machine...
... external switch to reset the drive. ... they have to have either seperate switches or contacts for each? ... Gecko or external? ... I connect all G320...
... the ... i would think the 6amp would be better. for gecko as you want to run 3 to 25 times the voltage. . with the 5.4 volt you could only do around...
I would discard the 2.83A one and instead consider the 6A motor. I assume these are NEMA-42 size motors; the 2.83A would have trouble getting out of its own...
Hi, I'm currently putting my new high speed machine into operation. It has five axes all equiped with servos and G320s. Although the performance is a bit below...
I connected 36V PS to pins 1 and 2. I measeured voltage between pins 3 and 4: zero volts. Is this correct?? I thought I should have the 36V present on G320...
I have just completed a 2-axis stepper system set-up, and the use of a servo-drive is all new to me. My goal is turn a large rotary table with a servo motor,...
I have 3 used Electrocraft DC brush servomotors, with Litton encoders attached. Four leads exit the encoder housing, one red, one black, one yellow, one blue. ...
I`ve set up my three geckos two are working perfect, but on one the motor just runs away, I removed it from my machine and set it up on the bench, same...
Maybe the one Gecko isn't supplying the +5V to the encoder. Check across enc- and enc+ to see if you are getting +5V. Check the known good ones the same way...
Mike, You need to connect a jumper between ENC+ and ERR/RES to enable the drive, fault light is off. Hook up your power supply and motor. With the encoder ...
OK, I picked up an HP1980B scope cheap cause it has a bad fan in it and figured I'd just replace the fan. Well the writing on the fan is smudged out but it's...
I have discovered that with a 5 volt supply it puts out 250 PPR. Is there a way to determine which of the two outputs is "A" or is this arbitrary? Grant ... ...
There have been (I can no longer find them on CAD_CAM_EDM_DRO) two circuits by Mariss to dump inductively generated motor energy to ground. Is either circuit...
On my HP 8640B function generators, it's a brushless DC fan (sort of like a stepper motor) that has a servo circuit to vary the speed to maintain constant...
OK, that makes sense. I've put my meter on it and it's giving 14v DC on 2 of the wires so I assume that a standard 12V brushless will do the trick. I guess...
