Description

P-AXIS-00568

Damping factor of natural frequency

Description

Besides the natural frequency itself, this parameter can also specify the damping factor of the natural frequency which is defined as follows:

P-AXIS-00571

Vibration Guard mode

Description

This parameter defines Modes 1 - 4 of the Vibration Guard function.

 

Modes 1– 3:

  • Asymmetrical modes (contours may have different forward and backward motions).
  • The higher the mode (1-3), the less sensitive to deviations from the actual natural frequency
  • The higher the mode (1-3), the larger the axis error (or contour deviation)

Mode 4:

  • Symmetrical mode (contours are identical in forward and backward motion).

 

Parameter
