Motor Current; Motor Frequency; Motor Power; Motor Voltage - Danfoss VLT 2800 Series Operating Instructions Manual

motor. The break points are set in parameters 423-
428 Voltage/frequency.
NB!:
Please note that if a value set in the name-
plate parameters 102-106 is changed, there
will be an automatic change of parameter 108 Stator
resistance and 109 Stator reactance.

M,N

(MOTOR POWER)

Value:
0.25 - 11 kW
Function:
Here you must set a power value [kW] P
sponding to the motor's rated power. The factory
sets a rated power value [kW] P
the type of unit.
Description of choice:
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.
