Parameters 493
97.19 Hexagonal field
weakening point
Defines the activation limit for hexagonal field weakening (in
percent of the field weakening point, ie. the frequency at
which maximum output voltage is reached). See parameter
97.18 Hexagonal field weakening.
Note: This parameter is only effective in scalar motor control
mode.

97.32 Motor torque
unfiltered
Unfiltered motor torque in percent of the nominal motor
torque.

97.33 Speed estimate
filter time
Defines a filtering time for estimated speed. See the diagram
on page 647.

98 User motor
parameters
Motor values supplied by the user that are used in the motor
model.
These parameters are useful for non-standard motors, or to
just get more accurate motor control of the motor on site. A
better motor model always improves the shaft performance.
98.01 User motor model
mode
Activates the motor model parameters 98.02…98.14 and the
rotor angle offset parameter 98.15.
Notes:
• Parameter value is automatically set to zero when ID run is
selected by parameter 99.13 ID run requested. The values
of parameters 98.02…98.15 are then updated according to
the motor characteristics identified during the ID run.
• Measurements made directly from the motor terminals
during the ID run are likely to produce slightly different
values than those on a datasheet from a motor
manufacturer.
• This parameter cannot be changed while the drive is
running.
Not selected
Not selected Parameters 98.02…98.15 inactive. 0
Motor parameters The values of parameters 98.02…98.14 are used as the
motor model.
1
Position offset The value of parameter 98.15 is used as the rotor angle
offset. Parameters 98.02…98.14 are inactive.
2
Motor parameters &
position offset
The values of parameters 98.02…98.14 are used as the
motor model, and the value of parameter 98.15 is used as the
rotor angle offset.
3
98.02 Rs user Defines the stator resistance R
S
of the motor model.
With a star-connected motor, R
S
is the resistance of one
winding. With a delta-connected motor, R
S
is one-third of the
resistance of one winding.
