AXIS#.OBS.BW

Description

AXIS#.OBS.BW sets the frequency at which the observer starts being the dominant component in the velocity signal.


    • To maintain stability, the Observer bandwidth should not be set lower than 3x the velocity open loop bandwidth (where the open loop blue line crosses 0dB).
    • This setting cannot be changed while the amplifier is enabled in order to minimize unexpected disturbances.
  • The Observer is made up of a few components. Following is a block diagram of how the Observer is connected in the loops.
