Hello Bob, we changed the nozzle z parameter until we got limit errors and backed up 1 mil. There was a slight reduction in the limit errors on the pickup of the component but it is still a problem. With the mod code we adjust the soft z height to ab

We have been having a recurring error on one of our Quad 4Cs. When it picks up the first of 8 47uF SMT capacitor it stops with a limit error. If we do 2 consecutive function 30s, the problem goes away until the next board. The first function 30 re

If its a tall part and you are trying to scan it lower than 200 or so...you can have this problem (limit error). Thinking of things to look at.....Is your z-rod spring sticking? Push up on it and it should spring back with NO hesitation...if it does.

If I have to guess then I would say the machine is first picking up a larger nozzle to pick up this part.....the nozzle is not seating on the z-rod correctly and causing a problem. Check to make sure the nozzle is being mounted correctly. You may als

Thanks Bob, I will change the z-rod just to make sure. It is a tall part read at 180. The nozzle height bugs me because we have 3 machines and the first one has a nozzle height of 238 while the 2 others around 200. I am thinking this parameter may ad

Quad4C's have their moments. If the price is right and you are aware of the machines limitations then you will be satisfied. The placement rate is slow, 1.2 seconds/chip. Don't buy any Quad if it has the CyberOptics Laser unit, the Quadalign unit is

If the feeders that you are having problems with have tall parts in them.....and these are the ones the machine is stopping on.....check to see that you are not scanning higher than what your function 30 nozzle height is. In other words...if your fun

I have had similar problems before where the machine will intermittently stop with a limit error. Reset the machine and away it goes. Replacing the ribbon cable that runs from the head (37 pin D-sub)has solved this problem. This cable gets flexed a l

I don't work on quads but I can give you some things to look for... Each of the moving axis work off a motor that is controlled by a "drive". Some of these drives have a fault or error output that is connected to the motion controller. One of your

Hello C.B. I am a former trainer/fse for that machine and still have a q1000 bible for fixing problems. I think the machine may need servo tuned to which there is a procedure that i would have to find. First thing to do though, is to drop the machine
