We identify the resonances in your system with SKF CMXA 80.

By the phase reference and vibration measurement, which are performed during the run up and cost down of the motor in variable speed systems such as fan applications and frequency converter applications, the resonance revolutions are established, and by remedying the aforesaid or by making their drive data entries, the operation of the system in the resonance fields is prevented, and the forbidden revolutions are established if balance adjustment will be performed onsite.
