Parameter 1-41 Motor Angle Offset
is automatically set when using PM motor and absolute encoder or re-
solver.
[7]
Enable in-
ertia run
Use this option to ramp up in the mode as specified in
parameter 1-01 Motor Control Principle
. Measured
inertia is set in
parameter 1-69 System Inertia
and
parameter 7-08 Speed PID Feed Forward Factor
is set to
90%.
Parameter 1-48 d-axis Inductance Sat. Point
Table 101: Parameter 1-48 d-axis Inductance Sat. Point
1-48 d-axis Inductance Sat. Point
Default value: Size related
Parameter type: Range, 1 - 500%
Setup: All setups
Conversion index: 0
Data type: Int16
Change during operation: True
N O T I C E
Run an AMA to set the value of this parameter. Edit the value manually only when the application requires a value other than
determined by AMA.
Select the d-axis inductance saturation point. The drive uses this value to optimize the performance of SynRM motors. Select the
value that matches the point where the inductance equals the mean value of
parameter 1-37 d-axis Inductance (Ld)
and
parameter
1-44 d-axis Inductance Sat. (LdSat)
, as percentage of nominal current.
Parameter 1-49 q-axis Inductance Sat. Point

1-49 q-axis Inductance Sat. Point
Default value: Size related
Parameter type: Range, 0 - 200%
Setup: All setups
Conversion index: 0
Data type: Uint16
Change during operation: False
N O T I C E
Run an AMA to set the value of this parameter. Edit the value manually only when the application requires a value other than
determined by AMA.
Enter the q-axis inductance saturation point. The drive uses this value to optimize the performance of IPM motors. Select the value
that matches the point where the inductance equals the average value of
parameter 1-38 q-axis Inductance (Lq)
and
parameter 1-45
q-axis Inductance Sat. (LqSat)
, as a percentage of nominal current.
