1-15 Low Speed Filter Time ConstRange: Function:Sizerelated*[ 0.01 - 20s]High pass-filter damping timeconstant determines the responsetime to load steps. Obtain quickcontrol through a short damping timeconstant. However, if this value is tooshort, the control becomes unstable.This time constant is used below 10%rated speed.1-16 High Speed Filter Time ConstRange: Function:Sizerelated*[ 0.01 - 20s]High pass-filter damping timeconstant determines the responsetime to load steps. Obtain quickcontrol through a short damping timeconstant. However, if this value is tooshort, the control becomes unstable.This time constant is used above 10%rated speed.1-17 Voltage filter time constRange: Function:Sizerelated*[ 0.01 - 1s]Machine Supply Voltage Filter Timeconstant is used for reducing theinfluence of high frequency ripples andsystem resonances in the calculation ofmachine supply voltage. Without thisfilter, the ripples in the currents candistort the calculated voltage andaffects the stability of the system.3.2.5 1-2* Motor DataParameter group 1-2* comprises input data from thenameplate on the connected motor.NOTE!Changing the value of these parameters affects the settingof other parameters.1-20 Motor PowerRange: Function:[2] 0.12 kW - 0.16 hp[3] 0.18 kW - 0.25 hp[4] 0.25 kW - 0.33 hp[5] 0.37 kW - 0.5 hp[6] 0.55 kW - 0.75 hp[7] 0.75 kW - 1 hp[8] 1.1 kW - 1 hp1-20 Motor PowerRange: Function:[9] 1.5 kW - 2 hp[10] 2.2 kW - 3 hp[11] 3 kW - 4 hp[12] 3.7 kW - 5 hp[13] 4 kW - 5.4 hp[14] 5.5 kW - 7.5 hp[15] 7.5 kW - 10 hp[16] 11 kW - 15 hp[17] 15 kW - 20 hp[18] 18.5 kW - 25 hp[19] 22 kW - 30 hp[20] 30 kW - 40 hp[21] 37 kW - 50 hp[22] 45 kW - 60 hp[23] 55 kW - 75 hp[24] 75 kW - 100 hp[25] 90 kW - 120 hp[26] 110 kW - 150 hp1-22 Motor VoltageRange: Function:Sizerelated*[ 50.0 -1000.0 V]Enter the nominal motor voltageaccording to the motor nameplatedata. The default value corresponds tothe nominal rated output of the unit.This parameter cannot be adjustedwhile the motor is running.Parameters VLT® HVAC Basic Drive Programming Guide3-8 MG18B222 - VLT® is a registered Danfoss trademark33
