it is a vision oplc. we have 3 machine that us it. the machine I am working on was going to have it but apparently it is now unavailable and i was directed to the v560 as it was the same size as the v260, had color screen, and was touch. what I mean by "did not make a difference" is that the problem stays with the output. No matter what motor/drive I connect or how I connect them to the outputs on the snap in the motors run inconstant. I removed only the v560 hmi. all other hardware stayed the same.

tried every thing above and did not make a difference. So for fun I swapped out the v560 hmi for a v260 that was running a motor just fine on a similar machine. After the swap out motor ran just fine. So now my question would be what is the difference between a 560 and 260.

I have tried most everything mechanical / hardware that I can think of to isolate the difference in performance. I have tried 3 different motors (4wire, 8 wire series , 8wire parallel). I have tried all the adjustment on the motor drives (type of motor, steps per rev, ect). I have 3 other machine that run the same snap in and I have switch the snap in with other machines. every thing I have tried leads back to 3 things. length/type of wire between output and motor drive, a difference in how the snap in and expansion outputs work, or I have a difference in the programing of the 2 outputs that I can not see. I have not tried to shorten the distance between the motor drive and the snap in, so that is on my list of things to try today. this test will at least remove the variable of length.

I am running a V570, v200-18-E5B, and IO-D16A3-TO16. the high speed outputs on the snap in and the expansion are both running identical stepper motor drives and motors. the motor that is controlled by the snap in has a long lag between button push and when it starts moving. It will not run at a constant speed and some times even stops and restarts with the button still pressed. the motor that is controlled by the expansion runs at a constant speed, stops and starts immediately with button commands, and runs must faster than the snap in controlled motor. stepper motor drives are set up the same (smooth 400, ect). the only difference between the 2 motors is the length of wire between the out puts and the motor drives. the snap in wire is 14' long and the expansion wire is about 2' long. Any ideas on how to smooth out the operation of the motor that is controlled by the snap in? CB v14 EOB 5-29.vlp

I am running v280, v200-18-e5b, and io-d16a3-to16. I am wondering why the high speed outputs are different between the snap in and the expansion modules? In the hardware configuration the snap in asks for 3 operands and the expansion asks for only 2.
