VLT ® 2800 Series010 Small display line 1.1(DISPLAY LINE 1.1)Value:See par. 009 Large display readout✭ Analog input 53 [V] [17]Function:In this parameter, the first of three data valuescan be selected that is to be displayed in theLCP control unit display, line 1, position 1. Thisis a useful function, e.g. when setting the PIDregulator, as it gives a view of process reactions toreference changes. The display readout is activatedby pushing the [DISPLAY STATUS] key.Description of choice:See parameter 009 Large display readout.011 Small display readout 1.2(DISPLAY LINE 1.2)Value:See parameter 009 Large display readout✭ Motor current [A][6]Function:See the functional description given under parameter010 Small display readout.Description of choice:See parameter 009 Large display readout.012 Small display readout 1.3(DISPLAY LINE 1.3)Value:See parameter 009 Large display readout✭ Feedback [unit] [3]Function:See the functional description given under parameter010 Small display readout.Description of choice:See parameter 009 Large display readout.013 Local control(LOC CTRL/CONFIG.)Value:Local not active (DISABLE) [0]Local control and open loop without slipcompensation(LOC CTRL/OPEN LOOP) [1]Remote-operated control and open loopwithout slip compensation(LOC+DIG CTRL) [2]Local control as parameter 100(LOC CTRL/AS P100) [3]✭Remote-operated control as parameter 100(LOC+DIG CTRL/AS P100) [4]Function:This is where the required function is selected if,in parameter 002 Local/remote operation, Localoperation [1] has been chosen.Description of choice:If Local not active [0] is selected, it is not possible toset a reference via parameter 003 Local reference.In order to enable a shift to Local not active[0], parameter 002 Local/remote operation mustbe set to Remote operation [0].Local control and open loop [1] is used if the motorspeed is to be set via parameter 003 Local reference.When this choice is made, parameter 100 Configurationautomatically shifts to Speed regulation, open loop [0].Remote-operated control and open loop [2] functionsin the same way as Local control and open loop[1]; however, the frequency converter can alsobe controlled via the digital inputs.Local control as parameter 100 [3] is used whenthe motor speed is to be set via parameter003 Local reference, but without parameter 100Configuration automatically shifting to Speedregulation, open loop [0].Remote-operated control as parameter 100 [4]works the same way as Local control as parameter100 [3]; however, the frequency converter can alsobe controlled via the digital inputs.Shifting from Remote operation to Local operationin parameter 002 Local/remote operation, while thisparameter has been set to Remote-operated controland open loop [1]: The present motor frequency anddirection of rotation will be maintained. If the presentdirection of rotation does not respond to the reversingsignal (negative reference), the reference will be set to 0.Shifting from Local operation to Remote operationin parameter 002 Local/remote control, whilethis parameter has been set to Remote-operatedcontrol and open loop [1]: The configurationselected in parameter 100 Configuration will beactive. The shift will be smooth.✭ = factory setting. () = display text [] = value for use in communication via serial communication portMG.28.E9.02 - VLT is a registered Danfoss trademark64
