Danfoss VLT DMS 300 Manual page 109

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 Voltage/frequency .
NOTE
Please note that if a value set in the nameplate
parameters 102-106 is changed, there will
be an automatic change of parameter 108
Stator resistance and 109 Stator reactance.
102 Motor power P
M,N
(MOTOR POWER)
Value:
0.18 - 4 kW
Function:
Here you must set a power value [kW] P
corresponding to the motor's rated power. The
factory sets a rated power value [kW] P
depends on the type of unit.
Description of choice:
Set a value that matches the nameplate data on the
motor. Settings between two sizes below and one
size over the factory setting are possible.
103 Motor voltage U
