MP2530 too large
Warning
You can use MP2520.x to compensate low-frequency oscillation (< 100 Hz)
on axes with mechanical problems.
However, HEIDENHAIN recommends that you avoid using MP2520.x if
possible.
Do not use for axes with belt drive!
You can also compensate disturbance oscillations with the band-rejection
filter:
7 7 7 7
Calculate the frequency of the oscillation and enter it in MP2550.x.
7 7 7 7
Increase the band-rejection filter damping in MP2540.x until the interfering
oscillation is minimized. Realistic input values: 3 to 9 [dB]
Note
The compensation dampens the control loop. Try first to remove the
mechanical causes of the disturbing oscillations.
To reduce the occurrence of disturbance oscillations, HEIDENHAIN
recommends the use of motor couplings with a low tendency to oscillate
(e.g. from the Rotex Company).
