TM 5-3895-374-24-1OptionsSpeed regulationMeasurement of the actual motor speed with a tachogenerator allows the speed to be regulated This being the case, automatic slip compensation depending on the load incorporated in the ALTIVAR ATV-45 2 is cancelled and replaced by the speed regulation loopThe speed regulation option ensures the following functions- adapting the voltage value provided by the tachogenerator,-developing the absolute value and the sign of the voltage signal to ensure regulation in bothdirectionsCAUTIONneither this adaptation circuit, nor that of the tachogenerator are isolated from the supplyAccuracy + 0,1 % of the maximum speed for - a torque variation from 0,2 Tn to Tn,- a speed range from 1 to 50/60PresentationThe speed regulation option is associated with the slow-down braking option (see p 62), and isavailable in two versions according to the power- a module reference VW3-A45101, or VW3-A451011,- a board reference VW3-A45201D90Installation and connectionsALTIVAR 0,75 to 30 kW : - installation and connection of the module: see p 68,- use the cable supplied with the option to connect the module to the J3connector of the control board,ALTIVAR 37 to 90 kW: - for mounting and connecting the board in the speed controller see p 70,- use the cable supplied with the option to connect the option board’s J5connector to the J3 connector of the control boardConnecting the tachogenerator- calculate the maximum voltage provided by the tachogeneratorEXAMPLE :motor 1800 rpm at 60 Hztachogenerator 0,06 V/rpmU = 0,06 x 1800 x 80 = 144 Vfrequency range 80 Hz60- using twisted cable, connect the tachogenerator to the option module or board terminals (J6connector),with values immediately above the value calculated, i e OV-145V in the example aboveSee following page for connection diagram for VW3-A45101 or VW3-A451011 module(page 3-223)
