Special motor mode
[8], if a special U/f set-
ting is needed that is to be adapted to the present
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

and 109
Stator reactance
.
102
102 Motor power P
M,N
(MOTOR POWER)
Value:
0.18 - 4 kW
✭
Depends on unit
Function:
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.
Description of choice:
Set a value that matches the nameplate data on the
motor. Settings between one size below (for FCD
303 two sizes below) and one size over the factory
setting are possible.
103
103 Motor voltage U
M,N
(MOTOR VOLTAGE)
Value:
50 - 999 V
✭
400 V
Function:
This is where to set the rated motor voltage U
M,N
for
either star Y or delta
1
.
Description of choice:
Select a value that corresponds to the nameplate
data on the motor, regardless of the frequency con-
verter’s mains voltage.
104
104 Motor frequency f
M,N
(MOTOR FREQUENCY)
Value:
24-1000 Hz
✭
50 Hz
Function:
This is where to select the rated motor frequency
f
M,N
.
Description of choice:
Select a value that corresponds to the nameplate
data on the motor.
105
105 Motor current I
M,N
(MOTOR CURRENT)
Value:
0,01 - I
MAX
✭
Depends on choice of motor
Function:
The nominal, rated current of the motor I
M,N
forms
part of the frequency converter calculation of fea-
tures such as torque and motor thermal protection.
Description of choice:
Set a value that corresponds to the nameplate data
on the motor. Set the motor current I
M,N
taking into
account whether the motor is star-connected Y or
delta-connected
1
.
106
106 Rated motor speed
(MOTOR NOM. SPEED)
Value:
100 - f
M,N
x 60 (max. 60000 rpm)
✭
Depends on parameter 102
Motor power, P
M,N
Function:
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.
Description of choice:
Select a value that corresponds to the nameplate
data on the motor.
