, to do this. Usual are 10% of the nominal current of the
motor. Plausible scenarios are listed in the following:
– Motor and/or load inertia are not known

a rough presetting of the Ks factor

n
Motor is freely movable

Execute Ks-measurement in speed or position control by a low speed
(< 100 U/min)
n
Motor has a limited travel path or a measurement at a specific position
m
If the travel path is limited or if the Ks measurement is to be executed at a spe-
cific position, the measurement in position control can be executed with an ad-
ditional periodical angle offset. This cyclical angle offset can be set via the
parameter

. Hereby, accordant to the required additional movement
between 5 and 20 degrees would be provided.
In general, can be said that an exact measurement has to be carried out during move-
ment, preferably, because otherwise the measurement is affected by friction.
Ks measurement with control loop analysis
The third method of the Ks measuring is appropriate for oscillatory systems and is de-
scribed in detail in the chapter
