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.

Notes :
• Parameter value is automatically set to zero
when ID run is selected by parameter
99.13 ID
run requested
. The values of parameters

…
98.12
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 data sheet from a motor manufacturer.
• This parameter cannot be changed while the
drive is running.

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.
