RoboticsIRBP APositionerThe ABB positioners are optimizedto be used for manipulating ofwork pieces in arc welding, ther-mal cutting and other applications.All axes can be fully coordinatedwith the robot when programmingas well as during operation.IRBP AThis positioner is for workpieces that have to be rotated aroundtwo axes to reach the optimal process position. It is suitable forapplications requiring one or two stations.The positioner IRBP A, which comes in three variants, is designedto handle workpieces including fixture of a weight up to 750 kg.The modular design, few and heavy-duty moving parts as wellas minimal maintenance demands make the positioner servicefriendly.Dynamically adaptive software plus high speed drives result in fastchangeovers and high productivity.General positioner featuresAll ABB positioners offer users a complete and efficient solution.They are of a robust design to ensure excellent stability and arewell protected for operation in harsh production environments.All positioners can be combined with any ABB six axes robotsexcept the small IRB 120.The positioners are easy to use with clear, simple instructionsfor programming. The control equipment is located in the robotcontroller and uses the same drive system and software as therobots.ABBs positioners are designed to be highly functional yetcompact to make maximum use of available floor space.Standardised dimensions for all rotating plates greatly simplifythe exchange of fixtures.Dynamic modelling allows rapid acceleration, fast movementsand re-orientation so that cycle times are kept to a minimum.The dynamic model automatically compensates for the effectsof gravity, inertia and friction to provide fast movements(QuickMove) and accurate following of the programmed path(TrueMove).The Load ID-function is used to calculate the centre of gravity andthe inertia of the workpiece and of the fixture.To meet requirements from our users the positioners can besupplied, or retrofitted, with a comprehensive range of pneumaticswivels (1 and 2 channels) and slip-rings (10 power signals andProfiBus).ABB positioner systems can be supplied with all necessary safetyequipment.IRBP ASpecificationVariantsHandling capacityMax continuous torqueRepetitive accuracy (r=500)Max rotation speedkgNmmm/sA-250250350+/-0.05150180A-500500650+/-0.0590150A-750750900+/-0.0590150Axis 1 Axis 2 Axis 1 Axis 2 Axis 1 Axis 2MeasurementsA-250A-500/1000 &A-750/1000ABC-100--100--DEFGHIJ900 1180700 1000800 1000900 1000900 1210 1293 910 440 1000 173950 1110 1457 1026 700950 1210 1457 1026 700950 1310 1457 1026 700950 1110 1682 1026 700950 1210 1682 1026 700950 1310 1682 1026 700------------A-500/1450 &A-750/1450700 1450800 1450900 1450For complementary information, please see the product specification.ABB reserves the right to change data without notice.
