Pleasenotethatifavaluesetinthenameplate
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:
0.25 - 22 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 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

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:
Setavaluethatcorrespondstothenameplate
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.
NB!:
The max. value equals f

107 Automatic motor tuning, AMT
(AUTO MOTOR TUN.)
Value:
✭Optimisation off (AMT OFF)
[0]
Optimisation on (AMT START)
[2]
Function:
NB!:
AMT is not possible on VLT 2880-82.
Automatic motor tuning is an algorithm that measures
stator resistance R
S
without the motor axle turning.
This means that the motor is not delivering any torque.
AMT can be used with benefit when initialising units
where the user wishes to optimise adjustment of
