VLT ® 2900 Series Select a value that corresponds to the nameplate data on the motor, regardless of the frequency converter's mains voltage. 24-1000 Hz Select Special motor mode [8], if a special U/f setting is needed that is to be adapted to the present motor. The break points are set in parameters 423-428 Volt- age/frequency . 50 Hz This is where to select the rated motor frequency f M,N . Select a value that corresponds to the nameplate data on the motor. NB! Please note that if a value set in the name- plate parameters 102-106 is changed, there will be an automatic change of pa- rameter 108 Stator resistance and 109 Stator reactance .
0,01 - I MAX Depends on choice of motor The nominal, rated current of the motor I M,N forms part of the frequency converter calculation of features such as torque and motor thermal protection. 0.25 - 22 kW Here you must set a power value [kW] P M,N , corre- sponding to the motor's rated power. The factory sets a rated power value [kW] P M,N , that depends on the type of unit. Depends on unit Set a value that corresponds to the nameplate data on the motor. Set the motor current I M,N taking into ac- count whether the motor is star-connected Y or delta- connected Δ. Set a value that matches the nameplate data on the motor.
Settings between one size below and one size over the factory setting are possible. 100 - f M,N x 60 (max. 60000 rpm) Depends on parameter 104 Motor frequency, f M,N For 200 V units: 50 - 999 V This is where to set the value that corresponds to the rated motor speed n M,N that can be seen from the nameplate data. 230 V For 400 V units: 50 - 999 V 400 V This is where to set the rated motor voltage U M,N for either star Y or delta Δ. Select a value that corresponds to the nameplate data on the motor. = factory setting, () = display text, [] = value for use in communication via serial communication port 20 MG.29.A3.02 - VLT ® is a registered Danfoss trademark Description of choice:
