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 .
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.
102 Motor power P
(motor power)
Value:
0.25 - 22 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
type of unit.
