Extended Setpoint ChannelExtended setpoint channel2.2.7 Suppression bandwidths and setpoint limitsDescriptionIn the range 0 U/min to setpoint speed, a drive train (e.g. motor, coupling, shaft,machine) can have one or more points of resonance, which can result in vibrations.The suppression bandwidths can be used to prevent operation in the resonancefrequency range.The limit frequencies can be set via p1080[D] and p1082[D]. These limits can alsobe changed during operation with connectors p1085[C] and p1088[C].p1091[D]...p1094[D]Suppressionbandwidthsp1101[D]p1083[D]p1083p1085[C](1083)Minr1084Speed limiting minp1080[D]y–1xp1082[D]Ï Ï ÏÏÏxy–1r1112Speed limiting maxxyr1119sollwertkanal_ausblendbaen_begrenzungen.vsdp1086D]p1086p1088[C](1086)Maxr1087Ramp-function generatorMotor controlFig. 2-10Suppression bandwidths, setpoint limitationFunction diagram overview (refer to the List Manual) 1550 Setpoint channel 3050 Suppression bandwidth and speed limiting© Siemens AG 2006 All Rights ReservedSINAMICS S120 Function Manual, 03/2006 Edition2-57
