P-05 Motor Cont. Rated Torque
Range: Function:
0.1 Nm * [0.1 -
10000 Nm]
Enter the value from the motor nameplate
data. The default value corresponds to the
nominal rated output. This parameter is
available when P-20 Motor Construction is
set to [1] PM, non salient SPM, i.e. the
parameter is valid for PM and non-salient
SPM motors only.
P-06 Base Speed
Range: Function:
1420
RPM *
[10 - 60000
RPM]
Enter the nominal motor speed value
from the motor nameplate data. The
data are used for calculating motor
compensations. n

slip
.
P-07 Motor Power [kW]
Range: Function:
4.00
kW *
[0.09 -
3000.00
kW]
NOTE
This parameter cannot be adjusted
while the motor is running.
Enter the nominal motor power in kW
according to the motor nameplate data.
The default value corresponds to the
nominal rated output of the unit.
This parameter is visible in keypad if
K-03 Regional Settings is [0] International.
NOTE
Four sizes down, one size up from
nominal unit rating.
P-09 Slip Compensation
Range: Function:
100
% *
[-500 -
500 %]
Enter the % value for slip compensation, to
compensate for tolerances in the value of n M,N .
Slip compensation is calculated automatically,
i.e. on the basis of the rated motor speed n M,N .
This function is not active when H-40 Configu-
ration Mode is set to [1] Speed closed loop or
[2] Torque Torque control with speed feedback
or when H-41 Motor Control Principle is set to
[0] U/f special motor mode.
P-10 Slip Compensation Time Constant
Range: Function:
0.10 s * [0.05 - 5 s] Enter the slip compensation reaction speed.
A high value results in slow reaction, and a
low value results in quick reaction. If low-
frequency resonance problems arise, use a
longer time setting.
NOTE
P-10 Slip Compensation Time Constant will not have effect
when P-20 Motor Construction = [1] PM, non salient SPM.
3.6.2 P-2# Motor Selection
Parameters to configure the drive to work with
Asynchronous AC Motor or Permanent Magnet Motor
P-20 Motor Construction
Option: Function:
Select the motor design type.
[0] * Asynchron For asynchronous motors.
[1] PM, non salient
SPM
For salient or non-salient PM motors.
PM motors are divided into two groups,
with either surface mounted (non salient)
or interior (salient) magnets.
P-24 Damping Gain
Range: Function:
140
% *
[0 -
250 %]
The damping gain will stabilize the PM machine
in order to run the PM machine smooth and
stable. The value of Damping gain will control
the dynamic performance of the PM machine.
High damping gain will give high dynamic
performance and low damping gain will give low
dynamic performance. The dynamic performance
is related to the machine data and load type. If
the damping gain is too high or low the control
will become unstable.
P-25 Low Speed Filter Time Const.
Range: Function:
0.01 s * [0.01 - 20 s] This time constant is used below 10%
rated speed. Obtain quick control through
a short damping time constant. However,
if this value is too short, the control gets
unstable.
P-26 High Speed Filter Time Const.
Range: Function:
0.01 s * [0.01 - 20 s] 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 gets
unstable.
P-27 Voltage filter time const.
Range: Function:
0.001 s * [0.001 - 1 s] 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
