Name [ID] Description Def.
[1157] magnetization curve. It is neccesary to disconnect the load from the motor shaft.
V/f ident.
standstill [1500]
Short standstill identification of motor parameters for V/f (scalar) control.
V/f ident. full
[1501]
Short identification of motor parameters with rotating motor for V/f (scalar) control.
After the START command the motor will rotate at the predefined speed to measure
the motor parameters. It is neccesary to disconnect the load from the motor shaft.
Direction test
[1502]
Short test of proper rotation direction.
Align pole
position [20]
Align pole position of synchronous motors. Brake is released during this
identification.
7.2.3 NAMEPLATE MOTOR PARAMETERS
Group of parameters number [1210]
Values obtained from motor macros or nameplate data.
MENU \ SETTINGS \ MOTOR \ NAMEPLATE MOTOR PARAMETERS
Name [ID] Description Def.
Motor type [1610]
Induction
motor
Induction motor Squirrel cage induction motor.
SMPM Synchronous motor permanent magnet.
Nom. power [357] Nominal motor power, read from the nameplate or catalog data. 1100 W
10 W ÷ 1,5E6 W
This parameter is required for correct calculation of power and proper operation of slip
compensation [348] (page 60).
Nom. voltage [59] Nominal voltage of the motor. 400,0 V
1,0 V ÷ 1000,0 V
During the installation, it is neccesary to check whether the motor connection (delta,wye)
voltage corresponds to this value. There is special case to shorten overload time the
motor, when it is allowed to set the wye voltage for a delta connection, while increasing
the values of nom. frequency and nom. revolutions to 173% of their original values.
Nom. frequency
[4]
Nominal frequency of the motor. 50,00 Hz
1,00 Hz ÷ 500,00
Hz
In the V/F control mode, this parameter determines the frequency at which the V/f voltage
curve reaches the value of End voltage [94] (page 58). Along with these parameters
determines the V/f curve voltage and frequency ratio - motor magnetic flux.
Nom. current
[151]
Nominal motor current, read from the nameplate or catalog data. 2,80 A
0,01 A ÷ 2000,00
A
This parameter determines the value of permanent motor current for motor overload
protection Motor overloading [27] (page 108).
Nom. revolutions
[356] Nominal motor revolutions per minute, read from the nameplate or catalog
data.
1450 rpm
100 rpm ÷ 30000
rpm
This parameter is important for proper operation of Slip compensation [349] (page 60)
and for calculation of motor pole count Nr of motor poles [1049] (page 47).
Motor power
factor [227]
Nominal power factor of the motor read from the motor nameplate or the
catalog data.
0,80
0,40 ÷ 1,00
Nom. torque
[1051]
Nominal mechanical torque on the rotor shaft calculated from the motor
nameplate data.

Pole pairs [1613]
Number of motor pole pairs calculated from the nominal rpms and the motor
frequency for induction motors, it is a parameter for synchronous motors.
