336 Parameters
98
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
. The values
of parameters
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.

1
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.
