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…98.12 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…98.12 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.

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.
Resistance value is given at 20 °C.
