text: <s>[INST] Error E64 (Kinetix 6000 2094-xxxx-x) Regarding E64 (Kinetix 6000 2094-xxxx-x), it happened in 5 axis of my production line (about 85 axis) Actually we see this issue every week. What we did: 1,For the 1st action, we used tie wrap to fasten feedback cable connector at motor end. This allowed us to run for 1 hr then stopped due to E64 again.2,For the 2nd action, we replace the feedback cable. This allowed us to run for other 2 hr, then stopped due to E64 again.3.For the 3rd. action, we replace the Kinetix This allowed us to run for other 2 hr, then stopped due to E64 again.4.For the 4th. Action we find the feedback low profile connector (Kinetix feed back cable connector) that we are having across the line The clam was holding the feed back cable isolation rubber not the exposed braided shield in some of the connector. We plan to turn the low profile connector clam over to hold all the servo motor feed back cable secure.5.for the 5th. Action Kinetix 6000 temperature too high.• Check for clogged vents or defective fan• Ensure cooling is not restricted by insufficient spare around the unit • Verify ambient temperature is not too high We try to cool down the servo motor 6.for The 6th. action, we replaced motor. This issue does not happen again until now.Type of defected motor :MPL-B540K-MJ24AAMPL-B540K-MJ22AA 1326AB-B720E-M2K7L According to Trouble shooting GuideE64 MotorFeedbackNoise (Mtr Fdbk Noise) is Noise on motor feedback cablePotential Cause is: Recommended grounding, per installation instructions, has not been followed. Possible Resolution is: Verify grounding.  Route feedback cable away from noise Sources.  Refer to System Design for Control of Electrical Noise Reference Manual(publication GMC-RM001).This issue stop my production line:544 min / 85 stop for MPL-B540K-MJ24AA 527 min / 24 stop for MPL-B540K-MJ24AA The input of Rockwell Esupport is: There are no known issues about these motors causing E64, feedback noise. Usually this type of fault is caused by the feedback cable or poor bonding for noise prevention. I am sure that these replacement motors are good, but if the problem comes back please inspect and clean the connector on the motor end of the feedback cable. I would also like to send to you a document on how to assemble the low profile feedback connector to verify that the shield is properly bonded to the cable clamp. Please advise. [/INST] According to your point #4, you show that you do not have the shielding properly bonded to the feedback connector. This is the path to ground for any noise that may be on the signal. Also make sure your motor power cable has the exposed shield under the clamp as well. Making sure that all components are grounded properly can help resolve this issue. Have tech support send you the feedback wiring recommendation that they mentioned. Are there AC line filters installed on the incoming line?Are there MOV's installed on your AC contactors?Are there MOV's/diodes installed on your DC contactors? All of these items can effect the noise on a signal line. \\n </s>
