0-76 DST/Summertime StartRange: Function:0 N/A* [0 - 0 N/A] Sets the date and time when summertime/DST starts. The date is programmed in the format se-lected in par. 0-71Date Format.0-77 DST/Summertime EndRange: Function:0 N/A* [0 - 0 N/A] Sets the date and time when summertime/DST ends. The date is programmed in the format selectedin par. 0-71Date Format.5.2.3 General Settings, 1-0*Define whether the frequency converter operates in open loop or closed loop.1-00 Configuration ModeOption: Function:[0] * Open Loop Motor speed is determined by applying a speed reference or by setting desired speed when in HandMode.Open Loop is also used if the frequency converter is part of a closed loop control system based onan external PID controller providing a speed reference signal as output.[3] Closed Loop Motor Speed will be determined by a reference from the built-in PID controller varying the motorspeed as part of a closed loop control process (e.g. constant pressure or flow). The PID controllermust be configured in par. 20-** or via the Function Setups accessed by pressing the [Quick Menus]button.NB!This parameter cannot be changed when motor is running.NB!When set for Closed Loop, the commands Reversing and Start Reversing will not reverse the direction of the motor.1-20 Motor Power [kW]Range: Function:4.00 kW* [0.09 - 3000.00 kW] Enter the nominal motor power in kW according to the motor nameplate data. The default valuecorresponds to the nominal rated output of the unit.This parameter cannot be adjusted while the motor is running. Depending on the choices made inpar. 0-03Regional Settings, either par. 1-20Motor Power [kW] or par. 1-21Motor Power [HP] ismade invisible.1-22 Motor VoltageRange: Function:400. V* [10. - 1000. V] Enter the nominal motor voltage according to the motor nameplate data. The default value corre-sponds to the nominal rated output of the unit.This parameter cannot be adjusted while the motor is running.VLT AQUA High Power Operation Instructions 5 How to programme the frequency converterMG.20.P3.02 - VLT® is a registered Danfoss trademark 1055
