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.
Parameter 1-46
Position Detec-
tion 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 specifies the saturation curve of the d- and q-
inductance values. From 20–100% of this parameter, the in-
ductances are linearly approximated due to
parameter 1-37 d-
axis Inductance (Ld)
,
parameter 1-38 q-axis Inductance (Lq)
,
pa-
rameter 1-44 d-axis Inductance Sat. (LdSat)
, and
parameter 1-45
q-axis Inductance Sat. (LqSat)
.
Parameter 1-70
PM Start Mode
[0] Rotor Detection
[1] Parking
[0] Rotor De-
tection
Select the PM motor start mode.
Parameter 1-73
Flying Start
[0] Disabled
[1] Enabled
[0] Disabled
Select
[1] Enabled
to enable the drive to catch a spinning mo-
tor in, for example, fan applications. When PM is selected, this
parameter is enabled.
Parameter 3-02
Minimum Ref-
erence
-4999.000–4999.000
0
The minimum reference is the lowest value obtainable by
summing all references.
Parameter 3-03
Maximum Ref-
erence
-4999.000–4999.000
50
The maximum reference is the highest value obtainable by
summing all references.
Parameter 3-10
Preset Refer-
ence
-100–100%
0
Enter the setpoint.
Parameter 3-41
Ramp 1 Ramp
Up Time
0.05–3600.0 s

parame-
ter 1-25 Motor Nominal Speed
for PM motors.
Parameter 3-42
Ramp 1 Ramp
Down Time
0.05–3600.0 s
