Simon, Normally that error is caused by a bad motor but also there is a possibility that a driver board or even the servo board are defective and last but not least check all your cables and connections. finally let me mention that you can also recei

I have a loud humming noise coming from my MY12 X-Motor ( Like when a motor is not locked in and it hunts). This noise is not all the time but only sometimes especially with fine placement!! What can it be? I do not want to change the Motor to find o

I'm having a problem with my Mydata My9 pick and place. Basically whenever I try to run the placement calibration program or try to have the machine find fiducials, or basically anything with precision, the machine displays a X MOT motor timeout erro

Possibly blocked air lines did you check air pressure? Also drivers on the relevant boards. or simply damage in the flexible wiring harness( a nightmare) sarason

Have you got a circuit diagram for your driver board? If not measure your driver into a resistive load and look for differences in current flow voltage drops under load dried out caps. Dead current measuring circuits etc. If you see an IC, look it up

From what you explain: 1. check all movements X,Y and Z are moving free while machine is off. 2. Resit all driver cards. 3. Check interface cables or boards. Not sure if Juki is using CAN or other interface standard, but random motor errors might be

hi pavel, If you are getting vibrate during fast mode, encoder or motor cable might be faulty. yes i faced the same problem in Juki KE2010 m/c. Try by replacing encoder & motor cable from Motor to driver unit. All the best

Check/reseat all connections on axis driver card and from driver card to step motor. On older MpM's it is common to get a bad connection on the connector for axis driver power and blow components on your driver board. Reseating these connectors mig

Hi Rob, Thanks for your fast response. In fact, after a better look to driver boards, it has leaking SMD Electrolityc caps. Unfortunately after replacing them in 3 units, one of them gives 90% of times, ALARM4 led ON. Looks like a comunication pro

I am assuming that the card that was changed was the motor driver card. Did they change the card with a known good board or just swap the X and Y cards. If they swapped cards it appears that the card that is now in the X motor slot is bad. Open the a
