Speed
50–9999 RPM
Size related
Enter the motor nominal speed from the nameplate data.
Parameter 1-26
Motor Cont.
Rated Torque
0.1–1000.0 Nm
Size related
This parameter is available when parameter 1-10 Motor Con-
struction is set to options that enable permanent motor
mode.
N O T I C E
Changing this parameter affects the settings of other pa-
rameters.
Parameter 1-30
Stator Resist-
ance (Rs)

Size related
Enter the value of the d-axis inductance. Obtain the value
from the permanent magnet motor datasheet.
Parameter 1-38
q-axis Induc-
tance (Lq)
0.000–1000.000 mH
Size related
Enter the value of the q-axis inductance.
Parameter 1-39

Parameter 1-42
Motor Cable
Length
0–100 m
50 m
Enter the motor cable length.
Parameter 1-44
d-axis Induc-
tance Sat.
(LdSat)
0.000–1000.000 mH
Size related
This parameter corresponds to the inductance saturation of
Ld. Ideally, this parameter has the same value as parameter
1-37 d-axis Inductance (Ld). However, if the motor supplier
provides an induction curve, enter the induction value,
which is 200% of the nominal current.
Parameter 1-45
q-axis Induc-
tance Sat.
(LqSat)
0.000–1000.000 mH
Size related
This parameter corresponds to the inductance saturation of
Lq. Ideally, this parameter has the same value as parameter
1-38 q-axis Inductance (Lq). However, if the motor supplier
provides an induction curve, enter the induction value,
which is 200% of the nominal current.
