WORD) Hex541 Extended status word (STATUS WORD) Hex544 Pulse count (PULSE COUNT)Function:These parameters can be read out via the serialcommunication port and the LCP display. See alsoparameters 009-012 Display readout.NB!:Parameters 515-541 can only be readout via an LCP control unit.Description of choice:Resulting reference %, parameter 515:Gives the resulting reference as a percentage in therange from Minimum reference, Ref MIN to Maximumreference, Ref MAX . See also Dealing with references.Resulting reference [unit], parameter 516:Gives the resulting reference in Hz in Open loop(parameter 100). In a closed loop the reference unitis selected in parameter 416 Process units.Feedback [unit], parameter 517:Gives the resulting feedback value with theunit/scaling selected in parameters 414, 415 and416. See also dealing with feedback.Frequency [Hz], parameter 518:Gives the output frequency from thefrequency converter.Frequency x scaling [-], parameter 519:corresponds to the present output frequency f Mmultiplied by the factor preset in parameter 008Display scaling of output frequency .Motor current [A], parameter 520:Gives the motor’s phase current measuredas an effective value.Torque [Nm], parameter 521:Gives the motor’s present load in relation tothe motor’s rated torque.Power [kW], parameter 522:Gives the present power absorbed by the motor in kW.Power [HP], parameter 523:Gives the present power absorbed by the motor in HP.Motor voltage, parameter 524:Gives the voltage being supplied to the motor.✭ = factory setting.
