I have a 842A AB absolute encoder that tells a setter(it holds brick) where it is at so It can set the brick in the proper location.
Basically It would travel one way and it would lose 2inches negative back at the home spot.
I was using an offset to limp it through till a new encoder arrived.
I installed the new encoder Tuesday. Reset eveything bam they were running like champs for 10hrs!!
Wednesday---I get a call saying the setter is not stacking in the right location. Sure enough the home position was off by 3.75inches. So I adjusted it in the offset while I look things over so they can run. Bam they ran all day long with no hiccups.
The ONLY thing that happened from Tuesday night when they stopped to Wednesday morning was the mechanic cut power off to the plc panel when he replaced i few hydraulic cylinders.
Now is there any way possible that scale factors in the plc can get screwed up or glitch or some **** when power is cycled. Because that is the only thing I can think of that cause this to happen. Because there is no other way for it to lose counts or slip.
Here is the
