Parameters 303
An optimization setting for balancing between control
performance and motor noise level.
Notes:
• This is an expert level parameter and should not be
adjusted without appropriate skill.
• Other settings than
may require derating. Refer to
the rating data in the
Hardware manual
of the drive.
Normal
Control performance optimized for long motor cables.
0
Low noise
Minimizes motor noise.
1
Rotor time constant tuning.
This parameter can be used to improve torque accuracy in
closed-loop control of an induction motor. Normally, the motor
identification run provides sufficient torque accuracy, but
manual fine-tuning can be applied in exceptionally demanding
applications to achieve optimal performance.
Note:
This is an expert level parameter and should not be
adjusted without appropriate skill.

25…400%
Rotor time constant tuning.
1 = 1%
Defines the relative output voltage boost at zero speed (IR
compensation). The function is useful in applications with a
high break-away torque where direct torque control (Vector
mode) cannot be applied.

0.00%
0.00 … 50.00%
Voltage boost at zero speed in percent of nominal motor
voltage.
1 = 1%
Motor model
temperature
adaptation
Selects whether the temperature-dependent parameters
(such as stator or rotor resistance) of the motor model adapt
to actual (measured or estimated) temperature or not.
See parameter group
for
selection of temperature measurement sources.
Disabled
Temperature adaptation of motor model disabled.
0
Estimated
temperature
Estimated temperature (
used for adaptation of motor model.
