Setting parameters04/07 AWB8230-1541GBSuppressing frequency rangesTo prevent resonances occurring in the drive system, you can, inaddition, program three frequency jumps under PNU A063 toA068.In the example (a fig. 95 ), the first frequency jump (PNU A063)is defined as 15 Hz, the second (PNU A065) as 25 Hz and the third(PNU A067) as 35 Hz. The jump widths (adjustable underPNU A064, A066 and A068) are set to 0.5 Hz in the example.A067A065A063f[Hz]f max352515baThe jump width (PNU A064) is the range above and below theselected frequency value (PNU A063). With PNU A063 set to 1 Hzand A064 to 15 Hz the range from 14.5 Hz to 15.5 Hz issuppressed.0tIn this example, the drive can be operated in the followingfrequency ranges:• 0 to 14.5 Hz• 15.5 to 24.5 Hz• 25.5 to 34.5 Hz• 35.5 to f maxStatic operation in the suppressed frequency ranges is notpossible.Figure 95: <strong>Frequency</strong> jumpsa Accelerationb DecelerationA064A064PNU Designation RUN b031= 10Value Function DSA063A064A065A066A067A068<strong>Frequency</strong>jump (1)<strong>Frequency</strong>jump (1) –jump width<strong>Frequency</strong>jump (2)<strong>Frequency</strong>jump (2) –jump width<strong>Frequency</strong>jump (3)<strong>Frequency</strong>jump (3) –jump width– j 0…400 Hz This function can be deactivated by entering 0.0. 0.00…10 Hz 0.50…400 Hz 0.00…10 Hz 0.50…400 Hz 0.00…10 Hz 0.592
