Note button 8 If the ATS finds a problem with signal calculation, the yellow Attention symbol
appears next to the Note button. Click the button to see a list of the problems
that have occurred.
Causes of problems may be:
 Excessive signal frequencies (high shaft speed of rotary encoder)
 Fluctuating speed (fluctuating frequency)
 Too small signal section to calculate the amplitude or the tolerance
Examples of notes:
Calculation of reference: Fluctuation of shaft speed - 3 times
Calculation of circle: Signal error - 24 times
Solution:
Attempt to traverse the encoders such that no "Note" is generated (Attention symbol), i.e. turn
the encoder shaft evenly and slowly.
