Re: Delta ASDA-B2 ACORN WIRING INFORMATION
It is not a good idea to have an inductive load (i.e. relay or contactor coil, DC motor, etc) without some means of protecting from the energy spike that results when the current is cut off. At best you will introduce noise that could interfere with the other equipment and at worst there is the poss...

Re: Help on isolation switch fit two circuits/power supplies
I can answer two of these: There should be formulae to calculate the required braking resistor or a table listing the values in the VFD manual. Depending on what series of VFD, it might have the braking resistor built in. You can assign one of the output relays to "SpindleCoolingFan" and i...

Re: Upgrading a Gorilla CNC from Flashcut to Acorn
Hello Daniel,
Glad you got one of the drives working! You're well on your way to having the machine up and running now.
We're happy to help!

Re: Upgrading a Gorilla CNC from Flashcut to Acorn
Hi Centroid467, As I understand from most replies I have received from the community, members do not clearly understand the subtle differences between Sink and Source output with common ground in Source configuration or common supply in Sink configuration. As an electronic circuit designer, I will ...

Re: Upgrading a Gorilla CNC from Flashcut to Acorn
Hello Daniel, You are right that the 74ACT125 tri-state buffers on the DB25 outputs will both sink and source current so wire them as in the DB25 drawings. I could not find any documentation on your specific drives and I suspect they might be a customized version for Gorilla CNC but from the 7th pag...

Re: Server motorsport run after update of CNC 12
Hello Steve, There should be a page in the Wizard under "DB25 Connector" labelled "Mapping". There will be a drop down menu to select DB25 or Screw Terminal near the top of the page. See page 95 in the ACORN installation manual for some nice pictures: https://www.centroidcnc.com/...

Re: Server motorsport run after update of CNC 12
Hello, I am taking a look at your report and I see that your CPU (Core 2 Duo P7570) is below our minimum requirements for good performance. However, I do not believe that is your main issue here. As it has been a while since the machine was last used, I would go through and verify that all the wirin...

Re: New build - Novakon Pulsar
Hello, If the spindle driver outputs differential quadrature encoder signals and the servo is belted 1:1 with the spindle then yes you should be able to use it for rigid tapping. If it is not belted 1:1 then you will need an encoder that is belted 1:1 with the spindle. Yes, there are gear ratio para...

Re: Can Centroid Control this?
Hello, I've seen some DC motors with both tachogenerator feedback and encoder feedback. I see a lot of references to "measuring system" inputs on the controller and they sure look a lot like encoder inputs to me. The language in the manual suggests that they are linear encoders on the axes...

Re: Can Centroid Control this?
I believe you would be able to control these with an Oak in velocity mode. The wiring would probably be a little annoying since it looks like you'll have to wire the encoders directly to the Oak rather than to the drive. From reading the manual, I would try wiring like this for velocity mode: pin 1 ...
