V2XT Handwheel encoder

[jrrhotrod]

Hey Guys
Ive got a v2xt sx machine that I am having problems with the jog wheel encoder. I have done some looking at the bourns and agilent optical encoders but I do not know enough about them to know which would be best as far as the pulses per revolution that I need. It Is going on the jog handwheel that controls the axis's and what I have now is an agilent optical encoder but I dont think it is the correct encoder because the table moves pretty harshly when the crank is turned like maybe the resulotion is wrong on it.If any of you could shed some light on optical encoders or maybe if any of you know what goes into the jog wheel on a v2xt machine I would greatly appriciate it
Thankyou....

The standard resolution for HWE is 100 pulses/rev. Most use TTL single ended, but Differential are available.
If you have the old one that has the detent mechanism, all you need to do is apply a 100p encoder, there are cheap ones by Koyo etc, If you need the whole mechanism, then surplus HWE come up on ebay all the time.

thanks Al I will check On them. I actually did some searching on my agilent encoder and It is a 100p/r maybe it is working properly but now Im just up in the air as to what might be wrong with my machine and why it responds to the movement of the jog wheel encoder so harshly I thought that it was to little of a pul\perrev and thats why the table jerked so bad when cranking.
thanks for the info

I am not familiar with that machine, but indent HW's are usually set up for a programmed move per increment, selected by Increment switch, e.g. .0001/incr, .001/incr, .01/incr, etc.
so one HW rev would give x100 the selected move/increment.
