Cat Number is MPL-B320P-MK22AA and P/N PN-11320 made in Poland I gear 3 axis together, this is the master moving with a MAM function using a Trapezoidal profile. I use the MRP function to redefine the position just before I lock the axis together and run. We are still testing this but we found that the timing belts wired cord are sticking out a little bit, and when it hitts the aluminium gear makes it a small power spark. It is that spark that makes the noise on the encoder, we cut the cord so it's inside the rubber and it fixed the problem. We have ordered a new type of belts without any cord inside and will test it later on. The thing we don't know is if the process is building up a super sharge that can be a bigger problem, but so far are everything looking good.

This may sound strange but it fixed our problem, we discovered that when using a timing belt is the motor shaft not properly grounded. Just to test it we mounted a grounded contact strip to the motor shaft and the problem disappeared. /Janne

Hello fellow programmers, Our system: Kinetix 6000, 3 axes with MPL-B320P motors On the motor shaft sits a small gear that feeds a bigger gear with a gear belt. On the other end of that shaft is it a other gear that is connected to a gear box by a gear belt. I am struggling with the E64 problem in our Kinetix 6000 system as well; I have worked with this type of system from late 2004. Our problem started approximate one year ago, the systems we are creating are very much the same all the time. I have used the same motor parameters from day one and never needed to make any tuning what so ever. We have had this problem at start in every system the last year but it has vanished after a few days of running, we think the systems get better after some time in particular when it's warm. The system I am working with right now is hopeless; I have changed 4 motors and new cables. Two motors was looking good at start but after app 30 minutes run did they shake like crazy (never happen before) but they did not fault, the other two are steady but they give me E64. In the past have we have this two gear belts really tight and really loose with no visible effect on the motion system. But for some reason is this looking as am major issue now days, I still don't have 100% proof on it except that I just setup one system, it was giving me E64 all the time and after losing up one of the gear belts did the problem disappear. I am curious if you have found a solution to this, or if you still got the problem. Btw E19 use to be related to position error and can be solved by tighten up the motor parameters or changing the position fault tolerance. Regards /Janne
