Thanks guys- All your answers give me a great understanding. Thank you !!! George -Metalmandude- ... explanation :) ... along ... pump ... PC ... constant ... ...
There's one thing they have forgotten, under susceptance type tests for CE it is arguable that it may be a legal requirement in Europe, and for the machine...
Hi Roger, I will work with Dental a soft from DELCAM. This soft will control all G code and select axis to go Sure it will much easy for me to work with G320...
Hi there - how should I wire up and configure the limit inputs on a Grex for use with Mach 3? I currently have +5v from the Grex routed out through some NC...
Hi Joe Hook up to pins on the Digital inputs of the GREX and join the common the GND. Go to Ports and Pins in MACH3 to the input signals tab. Tick enable for...
Hi Joe, What pin numbers are you using in Mach set up? I believe the x axis should be port #1, Pin 17. The y axis limit should be port#1, pin 18 and so...
Hi Joe, I believe that you take the limit pin from the G100 through the normally closed switch and then to ground. So the limit pin is held to ground until it...
Andre, Look at linuxcnc.org for a list of compatible hardware and specs. Mesa is at http://www.mesanet.com/. I think you are looking for a 5120. I'm not an EMC...
Arturo; Two places you can look for standards are NEC and IEC. Like Mark says, these cost mooney, but you can still find the relavent sections on the web if...
Thanks guys - I've swapped my limit switches over to switching 0v into the limit pins and configured Mach 3 accordingly, and everything works as it should :) ...
Hello I am using G320 to run a DC Servo. I have tuned the G320. The servo motor and the G320 are getting very hot! even just keeping the servo stationary. The...
Hi Jonny, what is the rated coil inductance of your motor. Is it an ironless bell or disc rotor type? It should be at least 0.5mH. Try adding an inductor of ...
Hi All, I have a hobby CNC setup with 3 G212 running inexpensive stepper motors (from HobbyCNC: 205oz-in unipolar rating, 3v, 3A; 33k resistor on the G212...
HI Bene Thanks, I think your suggestion will work! I got a inductor wound, but unfortunately it just melted in about 1min, as the core got way too hot. The...
Seems this could be done with tuning. Drawing that much current at idle indicates that the gain and damp are set improperly. The motor drawing current at idle...
Hi Jonny, try inductors used for high/low pass filters in multi way hifi audio speakers. They can take large currents. If you like to try winding your own you...
Hi all, I have been tunning my G320 servo drive for a big Fanuc motor every thing went perfect , I can jog smoothly accelerating and decelerating to full...
Servos and steppers too must ramp down to stop. If you're commanding a stop instead of pause or feedhold, the servo will lose position. Ron shadi_salhab_78...
Hi Ron Thanks for reply, but I don't think it has to do with the tuning, as the impulse response reads pretty close to the textbook example. Also I have...
Hi Bene Once again thanks for your response. I'm not sure where to get hold of the inductors you speak of, I have phoned around and none of the electronic...
Hi Jonny, the older driver probably uses recirculating PWM. This uses much lower duty cycles (near 0% at idle) resulting in less ripple and less heating....
... There are only a couple of possibilities. You have to differentiate between the inevitable AC current from the PWM carrier, and sub-PWM frequencies. If...
... J. W. Miller makes a wide variety of toroid inductors. Some of them are rated up to 15 Amps, although the inductance at that rating is small. Digikey,...
Hi guys - I guess this is a question that requires rather intimate knowledge of a Grex, but what actually happens when a limit switch is triggered? Does the...
Hi All, My apologies if it seems I can't contain my excitement! Mach now runs at 100kHz (and tested to 300kHz) which is excellent news for those servo heads...
Since your on the Gecko forum, the G100 will already do that and much more. I run 2500 RPM servos with 2500 line encoders quad encoded so that's 10,000 steps...
... Thanks Bene I am using a ferrite ring that I got wound, and it is doing an excellent job. My AC current has been reduced to between 0.3- 0.4 A. ...
Hello I would like my VB program that communicates with the G100 to respond to changes on the General Purpose Inputs. Is there a way that the G100 could...
