What do you hope to achieve by using the device please ?.

It appears to be a serial / parallel or parallel / serial converter of some sort but I am uncertain of it's application.

Thanks for the explanation, I understand now.

Do you have noise on the drive signals, limit switch inputs or the power lines ?.

No Tweakie for the moment i have not noise.

One time it happened that X axis made unexpected movement..!!

The manufacturer said that this system is designed to keep very low noise, so i think that is professional to have "AFC5".

Hi again,

I have searched the internet for more info on this assembled AFC5 device of yours without success.
My suggestion is that you forget about it - a dc to dc converter in itself would do little if anything to reduce any electrical noise in a CNC system anyway. If you feel that you have a noise problem then some very good tips have been detailed by Bob Warfield both here http://www.cnccookbook.com/CCCNCNoise.html as well as on this forum.

Sorry I can't be of more help.
Best regards,

Tweakie.
