suggested that the variation in external load inertia should be stable or slow. The convergence time
tuned in the auto mode varies by the speed of the change in motor rotation speed.
7.3.7. Resonance suppression unit
The excessive rigidity (system bandwidth set too high) of the drive control system could result in the
mechanical resonance generated by the drive combined with the machinery structure. The drive
provides the low-pass filter (PB-17), Notch Filter 1 (PB-10) and (PB-11), Notch Filter 2 (PB-12) and
(PB-13), as well as Notch Filter 3 (PB-10) and (PB-11). The resonance suppression is achieved without
affecting the original control parameter.
