Multi-step Speed References 1-15 Conflict with Jump Frequency

What does 086 mean?

This warning indicates that one or more of the multi-step speed references (A021-A035) are set to a value that conflicts with a defined jump frequency range (A063/A065/A067 ± A064/A066/A068). Operating at such a speed can cause mechanical resonance in the machine, potentially leading to damage or instability.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Perform vibration analysis to determine if resonance is actually occurring at the conflicted frequencies and adjust settings accordingly.
