3.2.7. Speed ripple

The typical speed ripple for a NX motor with a resolver at 4000rpm is 3% peak to peak.
This value is given as indicative data because depending on the settings of the drive
(gains of both speed and current regulation loops, presence of filtering or not, load
inertia, resistant torque and type of sensor in use), without external load (neither
external inertia nor resistant torque).
