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.
