Example
A plant has sympathetic vibration in the speed range from 520 Rpm to 580 Rpm. This
results in the parameter C11.0 = 550 Rpm and a range of C10.0 = 30 Rpm.
Figure 9-2 shows the interrelationship between the reference value progressions for a
skipped position. When the reference value reaches the lower speed range (in our
example: < 520 Rpm) the lower limit is output until the reference value reaches the upper
limit. The drive is then accelerated with the quick stop ramp until it reaches the upper
limit (580 Rpm).
With a decreasing reference value the jump occurs in the opposite direction (i.e., the
drive is held at the upper limit until the reference value reaches the lower limit).

In area to be
skipped
When the signal is high the motor speed is in the area to be skipped (C10.X,
C11.X).
