FCD Series
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
.
NB!:
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
✭
Depends on unit
Function:
Here you must set a power value [kW] P
M,N
,
corresponding 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 two sizes below and one
size over the factory setting are possible.
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
.
Description of choice:
Select a value that corresponds to the nameplate
data on the motor, regardless of the frequency
converter
’
s mains voltage.
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 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 features
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
.
106 Rated motor speed
(MOTOR NOM. SPEED)
Value:
100 - f
M,N
x 60 (max.
60000 rpm)
✭
Depends on parameter 104
Motor frequency, f
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.
