8.2.2 Speed blocking zones
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.
Definition of the blocking zones
The subcodes of codes
C00632 and C00633 can be used to define three zones which are to be
skipped by the output setpoint and which are to be passed as fast as possible by the ramp function
generator.
C00632/x
C00633/x

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.
L_NSet_1: Max. skip freq.
Maximum limit values for the speed blocking zones
• Selection of the maximum limit values for the blocking zones in which the speed must not be constant.
