VLT ® 2800 SeriesProgrammingline 2 when the frequency converter is switched on.The display will also be included in the scrollbarin display mode. In parameters 010-012 Displayreadout you can select a further three data values,which are displayed in display line 1.Description of choice:No readout can only be selected in parameters010-012 Small display readout.Resulting reference [%] gives, as a percentage,the resulting reference in the range from Minimumreference, Ref MIN to Maximum reference, Ref MAX .Reference [unit] gives the resulting reference with unitHz in Open loop. In Closed loop the reference unitis selected in parameter 416 Process units.Feedback [unit] gives the resulting signal valueusing the unit/scaling selected in parameter 414Minimum feedback, FB LOW, 415 Maximum feedback,FB HIGH and 416 Process units.Frequency [Hz] gives the output frequency ofthe frequency converter.Output frequency x scaling [-] equals the presentoutput frequency f M multiplied by the factor set inparameter 008 Display scaling of output frequency .Motor current [A] gives the phase current of themotor measured as an effective value.Torque [%] denotes the motor’s present load inrelation to the motor’s rated torque.Power [kW] gives the present power that themotor is absorbing in kW.Power [HP] gives the present power that themotor is absorbing in HP.Motor voltage[V] gives the voltage supplied to the motor.DC link voltage [V] gives the intermediate circuitvoltage of the frequency converter.Thermal load motor [%] gives the calculated/estimatedload on the motor. 100 % is the cut-out limit.Thermal load [%] gives the calculated/estimatedthermal load on the frequency converter. 100% is the cut-out limit.Running hours [Hours] gives the number of hours thatthe motor has tun since the last reset in parameter619 Reset of running hours counter.Digital input [Binary code] gives the signal statusfrom the 5 digital inputs (18, 19, 27, 29 and 33).Terminal 18 corresponds to the bit on the extremeleft. ‘0’ = no signal, ‘1’ = signal connected.Analog input 53 [V] gives the voltage valueof terminal 53.Analog input 60 [mA] gives the presentvalue of terminal 60.Pulse reference [Hz] gives the reference in Hzconnected to terminal 33.External reference [%] gives the sum ofexternal references as a percentage (sum ofanalogue/pulse/serial communication) in therange from Minimum reference, Ref MIN toMaximum reference, Ref MAX .Status word [Hex] gives one or several statusconditions in a Hex code. See Serial communicationin the Design Guide for further information.Heatsink temp.[°C] gives the present heatsinktemperature of the frequency converter. Thecut-out limit is 90-100°C, while cutting backin occurs at 70 ± 5°C.Alarm word [Hex] gives one or several alarmsin hex code. See Serial communication in theDesign Guide for further information.Control word [Hex] gives the control word for thefrequency converter. See Serial communication inthe Design Guide for further information.Warning word [Hex] gives one or several warningsin hex code. See Serial communication in theDesign Guide for further information.Extended status word [Hex] gives one or several statusmodes in Hex code. See Serial communication inthe Design Guide for further information.Communication option card warning [Hex] gives awarning word if there is a fault in the communicationbus. Only active if communication options are installed.If there are no communication options 0Hex is displayed.Pulse count gives the number of pulses thatthe unit has registered.✭ = factory setting.
