Thanks Al, I think that is kinda what I did by hooking up my test servo. (I know it works and it does have a normal 2 channel encoder with the index marker.) No resolvers or simulation ports to mess with..

I had no idea a multimeter would be able to see the encoder pulses if the mechanical action was slow enough. I am going to give that a try. I am embaressed to say my multimeter is a piece of junk.. (It is digital though).

How is Galil with problem boards like this? Built on a Friday?? LOL.. What really sucks is that the card has about 10 hours or less of total use and my warranty is about 5 months expired. (assuming it was a 1 year warranty. I dont even know what their policy on that is.) Guess I'll be calling tomarrow to find out what the repair cost will be..

Thanks for the advice AL,

Did you try the other, encoder inputs, if you have damaged one of the encoder inputs, it may be the similar to a 1700 card, I have one here and I could see if I can tell what kind of chips they use. Unfortunately they do not socket many IC's and you have to be carefull when replacing them, put an IC socket in when you do. The encoder IC's are usually not SMT type fortunately.
I would then look to the reason the inputs are blowing, as it will get expensive.

Al,
Im an idiot sometimes..
I will try the Y axis and see if that works...

When I first got the card, the inputs went bad the moment I closed the switch. Galil repaired it, sent it back, and the input was good while another one went bad. (just a jumpered wire to close the connection). Sent it back again, and they repaired it again. Its been good ever since. I have never had a single problem with the Contec Aux IO board I also have working in conjunction with the galil board.
Now, my inputs are good, but it seems that it wont accept an encoder signal now. Very strange... (and I did double check the cable between the ICM and the 1822)

Hmmm.. The walls seem to be closing in...

I had the same problem in July of last year on a DMC1860, except the encoder input was bad on arrival. This setup was using the a encoder simulation ports on Yaskawa drives. Galil specs these inputs up to 12V. With the encoder outputs going to the encoder inputs hooked up in any order should not damage the card, It will not count right but it should not damage the card. (This was the case I made when the comment "You hooked it up wrong" was made.)

Darek,

What is your general opinion about galil and their cards??

Just wondering, thanks for all your help and advice..

I have always found Galil support very helpfull, and like I mentioned before, I cannot recall having a failure on any Galil card I have used, I have used them going back to the DMC600.

The Galil cards are powerful motion controllers that are used in countless motion applications. The bad cards that I encoutered, one was hit by lightning and the second was made quick and sent out to replace it with no burn in period (This was the board mentioned earlier.). I have delt with these controllers on lots of automated processes and five other CamSoft installations and this is the only time I have had to replace one.

I also find Galil tech support to be very good, one tech in particular (Thanks MK!)

Thanks for the information.

Both of your opinions and testimonials carry considerable weight with me..
