Table of Contents◗TENSION CONTROLSWeb ProductsRSD DANCER CONTROL SYSTEMSAdvanced Technology for Simple Installation, Precise Control, and No Scheduled MaintenanceDancer Control SystemThe dancer arm stores web material in aloop, and maintains constant downstreamtension by increasing or decreasing theamount of material in the loop whenever theupstream web tension varies. The dancerarm performs best when it is kept in its midrangeposition, where it is always capable ofincreasing or decreasing the volume of webstorage, when reacting to tension changes.RSD Common FeaturesAll of the controllers are designed to workwith the Nexen DPS30 or 60 Hall EffectSensor to sense dancer arm travel througheither 30 or 60 degrees of arm movement.The RSD system works to maintain constanttension and keep the dancer arm inthe center of its travel range. If the dancerarm position changes, Nexen’s DPS DancerPosition Sensor, senses the movement andsends a signal to the RSD controller, whichprovides a corrective signal to the clutch,brake, or drive to increase or decrease webstorage and reposition the arm.Each controller is packaged in a sealedenclosure, operates over a 0 - 60°C [32 -140°F] temperature range, and is CE andETL approved.Nexen’s closed Loop dancer control systemsfeature the RSD Series of DancerControls for consistent web tension thatautomatically adjusts for changes in roll sizeand inertia. The four controls in this seriesare RSD100, RSD100P, RSD200, andRSD200P. The last product in this group isa complete unwind dancer control packagefor use with pneumatic brakes, the RSD250.the simple set up steps and even features adiagnostic screen to display, both graphicallyand digitally, the real time effects ofany tuning adjustments.The controllers can also provide either a4 – 20 mA or 0-10 VDC control output signalfor use with <strong>clutches</strong>, brakes, or drives.Each controller is capable of communicatingvia RS232 that allows commands to besent and status/data to be received viacomputer or programmable logic controller.Specifications RSD100, 100P & 200, 200P, Dancer ControllersPOWER SUPPLYISOLATED POWER SUPPLYOPERATING AMBIENT TEMPERATURE3109902354Conforms to ANSI/UL STD60950Certified to CAN/CSA=C.22.2 No.60950+24 VDC, 500 mA max+24 VDC at 500 mA15-24 VDC at 150 mA0°C to +60°C [32°F to +140°F]INPUTS Digital 12-24 VDC at 24 mA MaximumAnalog0-12 VDC at 1 mA MaximumOUTPUTSENCLOSURECABLEControl (Analog)Position SensorExcitation VoltageCommunications SoftwareSet up and calibration of the controllers isperformed with the Nexen CommunicationsSoftware installed on a computer.

Table of ContentsWeb ProductsRSD100, 100P, 200 & 200P DANCER CONTROLSMinimizes dancer arm movement and maintains running position.RSD100 Specific FeaturesThe RSD100 features automatic controlgain adjustment based upon roll diameterchange. As the roll diameter changes, theRSD100 can modify its control gainsautomatically, by observing changes in theoutput control signal level, or moreaccurately by using a roll diameter sensor.The roll diameter sensor is an ultra sonicranging sensor that senses the distancefrom the sensor to the surface of theunwind or wind up roll.The RSD100 uses a PID control algorithm,which is tuned with the NexenCommunications Kit.RSD100P Specific FeaturesThe RSD100P is an RSD100 equipped witha pressure sensor to sense the air pressurein the dancer arm’s loading cylinder. Thispressure signal provides the RSD100P withthe ability to adjust control gains automaticallyas the web tension is changed. Thiscontroller is recommended over the RSD100if web tension is changed more than +/- 20%.RSD200 Specific FeaturesThe RSD200 features automatic gain adjustmentbased on changes in roll diameter andinertia. Internally, the RSD200 utilizes a nonlinearadaptive algorithm that models an idealunwind or wind torque control application.Adjusting tuning parameters allows theRSD200 to adjust that model to fit theactual application. The end result is highperformance control without the need for theadditional feedback sensors common tomany drive systems.Simplicity is another feature of theRSD200. The basic system only requires adancer arm position sensor and a machinestart/stop signal to deliver high performance.TENSION CONTROLS ◗The adaptive algorithm also provides forSmart Splicing, which allows the RSD200to accommodate different size rolls duringsplicing without readjusting settings.The Super Crawl feature of the RSD200 givesit the ability to maintain stable performancewith small roll diameters and slow web speeds.RSD200P Specific FeaturesThe RSD200P is an RSD200 equippedwith a pressure sensor to sense the airpressure in the dancer arm’s loading cylinder.This pressure signal provides the RSD200Pwith the ability to adjust control gains automaticallyas the web tension is changed.This controller is recommended over theRSD200 if web tension is changed morethan +/- 50%.See next page for RSD250Unwind Dancer Package FeaturesRSD100, 100P & RSD200, 200P Approximate Dimensions55,42.1814,3.56Cable not shownCable Length 2 m78 inmmin.6,6.2627,71.092x O6,60.260MountingHoles123,194.85043,81.7211,6.46158,16.225,8.23102,74.04134,45.29Features• Control outputs of 4-20 mA and 0-10 V• 12 VDC reference output for Dancer ArmPosition Sensor• Inertia compensation• Accommodates Flying Splice Applications• Operating temperature of 0°-60°C [32°- 140°F]• PID control algorithm• Setup parameters adjusted via computer interface- No potentiometers to adjust• RSD control status available via RS232 communications• Designed for mounting anywhere on a machine• Drip proof and dust tight enclosure• No risk of hazardous voltages with 24 VDC operation• ETL & CE certifiedDANCER CONTROL SYSTEM POWER SUPPLYNexen’s +24 VDC power supply is compatible with the RSD100,RSD100P, RSD200 and RSD200P Dancer Control SystemsApproximateDimensions-VDC ONV.
