What Encoder Brands Do you use with your Ajax

[MILLMANM]

Looking for Info On encoder types That have been proven to work with Ajax
CNC systems.

Thanks for any info

I have seen Sumtak,Dynapar and Renco encoders used. They are 5 volt differential type. I will be trying some US Digital encoders that were on a Camsoft retrofit in the next couple of weeks and will let you know how they work. In my opinion the $125 that Ajax charges for a new encoder is money well spent. Terry

thanks for the reply, I went ahead and ordered the encoders from US DIGITAL # E6D hope they work,
Built mounts for my SEM motors over the week end at work so I
should know if they work some time this week.
Also had to change out the pin in the end of the motor. Went
from 5mm to .250 and .875 lenght to make it all work.
Seems that you have been doing some retrofits to ajax lately
any thing I shound look out for ?
Thank Brad

You can get Koyo encoders from Automation Direct.
A 5V TTL Quadrature encoder with 2500 PPR is around $75/80.
Lowest price I've seen and they work great.

do you mean line driver quads, 9 pin
if the US encoders work the are around the same money
for 2000ppr 8000 cpr and are easy install
thanks Brad

MILLMANN,

What model truck are you working on? could not help but notice it in the background.

What an eye , hate to change the subject , but it is a 69 f100 shorty
302 efi, aod, with 20" wheels, almost done, hope by the new year.

It looked like a E100 stubby at a glance.

I have finished wiring the US Digital E6D encoders to the system and they seam to work, in the pid parameters they show movement in all 3 axis, but it looks like I have to reverse the y axis to get it reading the right direction

[Al_The_Man]

Don't forget that if the motor direction is right but the encoder is wrong direction, on a differential type you just swop the A & /A pins.

MillManm,

You do not need to change the encoder wiring at all with an Ajax system. The control does not care which direct the encoder reads, as long as it reads correctly and smoothly.

Just swapping the A & A/ will do nothing at all, except not work. The correct proceedure to change encoder direction is to swap the A & B and the A/ & B/.

[Al_The_Man]

I guess I am used to all the motion control cards that I use that use this method, I was not aware that AjaxCnc would be different. Sorry for the mislead.
