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 motor spin-
ning due to mains drop-out. Select
[0] Disabled
if this function
is not required. When this parameter is set to
[1] Enabled
,
pa-
rameter 1-71 Start Delay
and
parameter 1-72 Start Function
are
not functional.
Parameter 1-73 Flying Start
is active in VVC
+
mode only.
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 lowest obtainable by summing
all references.
Parameter 3-41
Ramp 1 Ramp
Up Time
0.05–3600.00 s
Size related
If asynchronous motor is selected, the ramp-up time is from 0
to rated
parameter 1-23 Motor Frequency
. If PM motor is selec-
ted, the ramp-up time is from 0 to
parameter 1-25 Motor Nom-
inal Speed
.
Parameter 3-42
Ramp 1 Ramp
Down Time
0.05–3600.00 s
Size related
For asynchronous motors, the ramp-down time is from rated
parameter 1-23 Motor Frequency
to
0
. For PM motors, the
ramp-down time is from
parameter 1-25 Motor Nominal Speed
to
0
.
Parameter 4-12
Motor Speed
Low Limit [Hz]
0.0–400.0 Hz
0 Hz
Enter the minimum limit for low speed.
Parameter 4-14
Motor Speed
High Limit [Hz]
0.0–400.0 Hz
100 Hz
Enter the maximum limit for high speed.
