12.2.4 Skip frequency function
If the speed setpoints in speed-variable drives are linearly increasing, for instance, the frequency/
speed range is divided into a number of equal time segments. Therefore, there may be speeds
during acceleration time which must be bridged very fast (e.g. natural resonant frequencies).
The skip frequency function offers the opportunity to select a range in which the initial speed is
maintained. If the speed setpoint leaves that range, the drive will be accelerated to reach the
desired speed.

Note!
• Skip frequencies only affect main setpoints.
• It is not possible to exclude "0" speed if there is a sign reversal of the speed setpoint.
