3.2.9. Speed ripple
The typical speed ripple for a EX 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).
