MY12 F-MOT-MSETDYN x/12: Position Counter Dead

I'm surprised MyData is pushing the service call. They're usually pretty good at walking you through some troubleshooting steps before going straight to the service call.

So, the failure sounds like an encoder failure; the encoders are attached to the motors, and failures could be a result of a bad connection, a bad motor, bad encoder, or bad MOT card (there's a chance of a problem somewhere in the power supply/booster circuits, but that's an outside shot).

To isolate...start by getting into the service menu, where you can load the motor controller software independently. Load the software, and initialize each motor controller. This should confirm the X-MOT failure. Then, swap MOT cards. If the failure moves with the MOT card (swap MOT X with MOT y, for example), your issue is a MOT card, and not a motor problem. If the problem does not move with the MOT card, your issue is likely to be a motor/encoder problem, or an interconnect problem.

Double check all of your connections on the head, and to the motors....reseat all of the connectors. Ensure that the ribbon cable connected to the head is in good repair. Make sure nothing is impeding the X axis movement.

The upside to a MyData service call is that there are a number of things that can go wrong, and if you buy all the replacement parts, it's pretty expensive. If the tech does the work, MyData will let you return the parts that you don't need (he's likely to get there, and tell you to order a MOT card, a motor, and potentially some other things). The downside is it's a multi-day affair (since the techs don't bring any of the major parts with them), costing more money for the service call.

Good luck!

It could very well be the Safety Relay located inside the ELMO PSU (Bottom left in computer cabinet). I just had the same problems on 2 MY9's within 2 months apart. the Part cost around $700.00 from Mydata (Now Mycronic). These fail commonly with older machines. If you are familiar with the extended service menus you can go in and independently move both the X-Wagon Motor and the X-Belt Motor. Both have encoders/Motors. If both do not move then this rules out the motors and encoders because they are independent. In the extended service under board select option for MOT X (X board). Then select motor test. in this menu you can pulse both motors independently. If you want to call me I can help you through this. (540)362-8466 ext.1063 My name is Steve.
