Parameter 1-26 Motor Cont.
Rated Torque
0.1–1000.0 Nm Size related This parameter is available when parameter 1-10 Motor
Construction is set to options that enable permanent
magnet motor mode.
NOTICE
Changing this parameter aects the settings of
other parameters.
Parameter 1-30 Stator
Resistance (Rs)
0–99.990 Ω
Size related Set the stator resistance value.
Parameter 1-37 d-axis
Inductance (Ld)
0.000–1000.000 mH Size related Enter the value of the d-axis inductance. Obtain the value
from the permanent magnet motor datasheet.
Parameter 1-38 q-axis
Inductance (Lq)
0.000–1000.000 mH Size related Enter the value of the q-axis inductance.
Parameter 1-39 Motor Poles 2–100 4 Enter the number of motor poles.
Parameter 1-40 Back EMF at
1000 RPM
10–9000 V Size related Line-line RMS back EMF voltage at 1000 RPM.
Parameter 1-42 Motor Cable
Length
0–100 m 50 m Enter the motor cable length.
Parameter 1-44 d-axis
Inductance 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
Inductance 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.
Parameter 1-46 Position
Detection Gain
20–200% 100% Adjusts the height of the test pulse during position
detection at start.
Parameter 1-48 Current at Min
Inductance for d-axis
20–200% 100% Enter the inductance saturation point.
Parameter 1-49 Current at Min
Inductance for q-axis
20–200% 100% This parameter species the saturation curve of the d- and
q-inductance values. From 20–100% of this parameter, the
inductances are linearly approximated due to
parameter 1-37 d-axis Inductance (Ld), parameter 1-38 q-axis
Inductance (Lq), parameter 1-44 d-axis Inductance Sat.
(LdSat), and parameter 1-45 q-axis Inductance Sat. (LqSat).
Parameter 1-70 Start Mode [0] Rotor Detection
[1] Parking
[0] Rotor Detection Select the PM motor start mode.
Parameter 1-73 Flying Start [0] Disabled

Frequency.
Parameter 3-42 Ramp 1 Ramp
Down Time
0.05–3600.0 s Size related Ramp-down time from rated parameter 1-23 Motor
Frequency to 0.
