3.3.6 1-2* Motor Data
This parameter group contains input data from the
nameplate on the connected motor.
NOTICE
Changing the value of these parameters affects the
setting of other parameters.

Function:
[0.01 - 20 This time constant is used above 10%
rated speed. Obtain quick control
through a short damping time
constant. However, if this value is too
short, the control becomes unstable.
Function:
[0.001 - 1 Reduces the influence of high
frequency ripple and system resonance
in the calculation of supply voltage.
Without this filter, the ripples in the
currents can distort the calculated
voltage and affect the stability of the
system.
Function:
motor operation.

NOTICE
This parameter cannot be adjusted
while the motor is running.
Enter the nominal motor power in kW
according to the motor nameplate data.

Function:
[ 0.09 - Enter the nominal motor power in hp

hp] The default value corresponds to the
nominal rated output of the unit. This
parameter is visible in LCP if
parameter 0-03 Regional Settings is [1] US.
Function:
[ 10 - Enter the nominal motor voltage

data. The default value corresponds to
the nominal rated output of the unit.
Function:
[20 - Minimum to maximum motor frequency: 20–
1000 590 Hz.
Hz] Select the motor frequency value from the
motor nameplate data. If a value other than
50 Hz or 60 Hz is selected, adapt the load-
independent settings in parameter 1-50 Motor
Magnetisation at Zero Speed to
parameter 1-53 Model Shift Frequency. For 87
Hz operation with 230/400 V motors, set the
nameplate data for 230 V/50 Hz. To run at 87
Hz, adapt parameter 4-13 Motor Speed High
Limit [RPM] and parameter 3-03 Maximum
Reference.
Function:
[ 0.10 - Enter the nominal motor current
10000.00 A] value from the motor nameplate
data. The data are used for
calculating torque, motor overload
protection, and so on.
