5. Recommended speeds
This field shows recommended rotation speeds. The best values are found on the left side. Each entry has the form Min..Nominal..Max
The nominal value is in the middle between minimum and maximum. It should be used preferably.

Diagram

 
6. Diagram
 
The horizontal axis shows the entered rotation speed range. The blue line marks the recommended speed. You can see from the diagram why this speed has been chosen:
  • Angle stability: Resonances result in changeable phase angles. There are three colored bars for angle stability. The green bar indicates best values below +/- 5 %.
  • Dominant unbalance signal: Unbalance vibration is only one component in a mix of other frequencies. The higher the difference between unbalance vibration and other vibration the better the chance of good balancing results. A value of 100 % in the U/E diagram would mean that there is no other signal than unbalance vibration.
