Measures against system resonances
The combination of a motor and the involved mechanical
drive components are forming a typical spring/mass system
that can oscillate if the damping of the mechanics is insuffi-
cient.
Stepper motors resonance appearances are possible. In a
worst
case situation the stepping motor will stall with a
whistling sound.
An effective countermeasure against this kind of resonances
are da
mping elements which are for typically installed on the
extended motor shaft.
For precision position tasks we always recommend the use of
th
is damping measure.
A cause for resonances are often overdimensioned motors. In
this case we suggest to reduce the torque via the motor pa-
rameter umotmin/umotgrad or choosing a more suitable
motor.
