This frequency can be extracted for the “DEVIATION”
curve in “Motion Diagram” (refer to chapter
Move Axis Motion Diagram) if the ratio between load
and slider load is sufficiently high.
If this is not the case, this frequency can be
determined with the help of a highspeed camera, an
acceleration sensor or a smartphone app for vibration
measurements.

F Setting
The band width of the position control (GAIN POS)
should be set as high as the movements can be
completed within the tolerable position deviation but
before the motor begins to oscillate. In some
applications, usually with high payloads, it sometimes
happens that no setting can be found that meets
both criteria. If the motor with a set band width
begins to oscillate because of a resonance in the
system, this oscillation can possibly be suppressed
with a filter.
In the menu „state controller“ in WebMotion® the
correct PAYLOAD and the required GAIN POS have to
be set. If the motor oscillates, the resonance
frequency can be found and suppressed with the
frequency analysis function.

, the frequency analysis pops
up.
When operating, the frequency analysis can be
started anytime. But because the current of the
motor is being analyzed for the frequency analysis
the, the output stage must be turned on. As soon as
the analysis is completed, the measuring results are
shown in WebMotion® and the frequency can be set.
