Record resolution The amount of time between consecutive sampling
points. This value is calculated in conjunction with
maximum recording time. With the Composer Wizard,
the maximum number of recorded data points is 8000.
The record time length is calculated as:
8000/(number of values) * record resolution.
Resonance A condition whereby a large oscillatory amplitude
occurs as a result of a small amplitude of periodic
input, with a frequency close to one of the regular
system frequencies. For example, a motor has a load
whose transfer function has the Bode plot depicted in
Figure
G-2. It has a local maximum at the frequency
100 Hz; therefore, it can be said that the motor and load
have a resonance frequency of 100 Hz. The systems
absorbs energy at its resonance frequencies, thus
tending to oscillate at those frequencies unless the
controller is well designed to eliminate this
phenomenon.

Function Including Resonance
Smooth factor The time, in milliseconds, that a motion speed profile is
curved. The degree to which the “sharp corners” of a
motion speed profile are curved. Smoothing a profile
increases the time required to complete the motion.
