Using new speed forward-feedback function

Using new speed forward-feedback function



forward-feedback


Notice Beforehand

  • Please double-check that you did not change any parameters before starting using speed forwardfeedback function.

  • Or, please set default value.

  • Please move the mechanical parts into middle to leave enough space for three circles of motor rotation.



Guidance on how to use speed forward-feedback function


Enter into concealed parameter

1. Press keys in turn on the panel as ‘Inc, Dec, Dec, Inc, Enter’ under bb status to open concealed parameter.

panel








2. Enter Fn008.

  1. It displays "J" on the panel. Then press "mode" key on the panel to start inertia ratio auto reading.
  2. The motor will then rotate forward CW 3 circles and rotate reverse CCW 3 circles.
  3. The inertia will then be automatically written into Pn124.


Set following parameter

  1. Set Pn012 as 1.
  2. Increase Pn120.



Effected.

  • Now the speed forward-feedback function has been engaged. You can then start to adjust Pn013,Pn014,Pn018,Pn120 and so on according to your application requirements of robustness & noise.

  • Please turn to servo parameter adjustment methods for more reference.
