Hi I have 4 rotary encoders i need to start a project with these I'm thinking
Digital Readout for my metal lathe... but i need some help... i have technical documents, but i don't know were to start, any help is appreciated

thank you

tell us more, you have encoders but no display/counter? There used to be someone who sold encoder counters for some of the Chinese encoders, but I don't remember the name right now. You could change those counters to work with normal quadrature encoders if I'm remembering correctly.

If these are incremental quad encoders see this link for a diy DRO.

I still have the sofware up on my website (updated) for the lindsey dro that uses a dos based computer to interupt and display the values.

It might also give you some ideas of the trials and tribulations of the setup.

Hi ...this information you guys provided reminds me why im addicted to this website thanks to all of you..... here is technical data for the encoders i have to do more research on the spects

Frank

As you can see from the specs, be aware that Heidenhain can be 5v square wave or low signal sinewave. The Sine wave require a less common interface type.

Hi AL thanks for the help....I have a limited knowledge of electronics but i think i can pull this one off with a little help.. i don't understand what the difference is between 5v square wave and low signal sine wave. here is the pictures of the encoder wiring.I'm not sure how to wire it with the hard ware setup Giff below i also have an encoder interface i dont know what it is or if its usefully.
I'm hoping the transistors i bought at radio shack will work spects are below

What is the part number of the encoder? I can tell you what the output is if you are in doubt.
You will need different interface logic for each type.

what is the ROD/RON# ?
Al.

[frankg521]

Sorry al Rod 523 /1003 09000

Frank

[Al_The_Man]

Your in luck they are 5v TTL.
I guess you figured that out from the sheet you posted.

HI Al i have no clue how to wire this encoder their are 12 wires on this encoder cable i don't know witch on is for CHB...5V...CHA...GND

Frank

[Al_The_Man]

The DIY DRO that you are interested in, only uses the 5v and common and the A & B signal, so this is only four conections from the encoder.
Some have a connector and some are hardwired, I will list both.
The ROD 525 connections you want are:
D or Brown/Green = +5v
F or White/Green = 5v common
A or Brown = A Pulse
B or Grey = B pulse
The rest, tape up.

Al you are the man how did you find this information iv been looking for weeks

[Al_The_Man]

Al you are the man how did you find this information iv been looking for weeks

I had a habit of amassing manuf. cat. etc back when they used to publish and send them out to users.
It has turned out very usefull when looking at older/legacy items on ebay, etc.
Actually, Heidenhain is one of the few that is very good at getting information by emailing them in a pinch.

Thats great Al ....I'm going to wire it right now ...could you sent me the docs they sent you?? [email protected] thank you very much

HI al
I wired 1 axis for testing but no joy i double checked all connections i have 5 volts at the encoder how do i diagnose this circuit

Frank

I have windows 2000 on a dell laptop could that be the problem
