2nd Multi-step Speed Reference 0 Conflicts with Jump Frequency

What does 285 mean?

For the second motor settings, this warning indicates that the 2nd Multi-step speed reference 0 (A220) or output frequency (F001) is set to a value that falls within one of the defined 'jump frequencies' (A063/A065/A067) with its associated width (A064/A066/A068). Operating at such a speed can lead to mechanical resonance or unstable operation for the second motor at that frequency.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   If the jump frequency is critical to avoid resonance, then select a different multi-step speed for operation of the second motor.
