text: <s>[INST] MAM (motion axis move) ERROR Summary: Intermittent MAM.ERI have 2 servo driven linear transfer slides that faults out several times per week. When this happens I have found that the MAM is in ER condition. The only thing that I can find in the vast array of tags is MotionControl[1].ERR = 5. Anyone have any ideas what is causing this. Also, there are 2 of these servo drives and it is happening on either one, but not both at he same time. AXIS_SERVO_DRIVE AMP= 2094-AMP5 MOTOR= MPL-A230P-Vxx2 MotionControl[1].ERR = 5 [/INST] Larsen, you can find more information using the help file with Logix 5000 or Logix Designer. If you go to MAM in the help file, then go near the bottom of the entry, there is SEE ALSO and a hyperlink to Motion Error Codes (.ERR). Click that link to see a table of error codes. Error code 5 is telling you that the MAM instruction is being called before the servo drive has been turned on (it needs an MSO instruction to execute first). One way to prevent this error from occurring is to add a condition making sure that the servo has been turned on. For example, if your axis was called LINEAR_X, then you'd have an XIC instruction checking LINEAR_X.ServoActionStatus. If the ServoActionStatus bit is true, then error 5 will not happen. You should also examine the logic leading to the MAM to make sure that the MSO instruction is getting called properly. Let us know if you need more help. TJ McDermott Systems Interface, Inc. \\n </s>
