Ajax on Hurco

[please no smoke]

Anybody do an ajax kit on a hurco? I received my kit last week and documentation is a little thin. Scott is helping me but I'm not sure if he has seen my setup before.

The stock pinouts for the encoders are shield, +LS, -LS, A not, B not, marker, +5, and GND. The pinouts on the provided ajax kit are A+, A-, B+, B-, Z+, Z-, +5v, COM, and N/C. I don't know what to connect to what?? Anybody??

I think this will be a good kit but the road to cutting chips may be long.

thanks

Are the servo motors silver or black?

[please no smoke]

black electro craft e 252 or 262 i can't tell

Well normally I would say "Marker" is the Z, COM is GND, A not= A-, B not= B- but it seems the number of connections is not the same.

Differential encoder signals are more stable in a noisy environment.

Good Luck.

The last Hurco retrofit I did had the silver motors with a 1/2" shaft in back of the motor. I replaced the 200 or 250 line encoders with the Ajax 2000 line encoders. It was money well spent.

I was afraid someone would tell me I need to spend more. My only thought is that the A theta, B theta that I called a not are the A+ and B+ and the rest are tied to a common ground???????

What I don't understand is that in the online manual from AJAX they have this:

.....
REQUIRED by the CPU7 card. A list of the wires necessary for their operation is listed below:
A B I +5V Shield
Anot Bnot Inot GND
II. TTL: These encoders have fewer wires making


I don't see the Z, Z- that the AJAX drawing has. Did you buy the new encoders because you could not figure the old wiring out??

[cncsnw]

"I" and "Inot" are a creative way of saying "Z" and "Z-". "I" for "index".

You may also see "C" and "C-", or "+Z" and "-Z", or "marker" and "/marker", etc..

I have no idea what "LS" would stand for when coming from an encoder, though....

[converterk]

What is the shaft size of the encoders on the black motors?

[please no smoke]

1/4" shaft per drawing and it looks that way. Supposed to be a litton encoder per my manual but I tore it apart and it's and optical BEI motion systems 82BZ-1000-5-1. Only 5 wires in the plug.

LS is limit switch. They run them back on the same cable as the encoder. Well mat least on mine they did.

For the record. It appears that for the Ajax kit to function you need to have "modern" encoders A, A-, B, B-, Z, Z-, etc.

No Smoke,

How's it going ? Are you about there?
