Danfoss VLT 2800 Series User Manual

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
M,N
(motor power)
Value:
0.25 - 22 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 and one size
over the factory setting are possible.
103
Motor voltage U
M,N
(MOTOR VOLTAGE)
Value:
For 200 V units: 50 - 999 V
230 V
For 400 V units: 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 ac-
count 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 parame-
ter 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.
