NOTICE
This parameter cannot be adjusted while
the motor is running.
This parameter defines the term clockwise
corresponding to the LCP direction arrow. Used for
easy change of direction of shaft rotation without
swapping motor wires.
the frequency converter is connected U⇒U, V⇒V,
and W⇒W to the motor.

V⇒V, and W⇒W to the motor.

type of the feedback device. This option sets the
frequency converter to use the motor angle
offset entered in parameter 1-41 Motor Angle
Offset, if an absolute feedback device is used.
If an incremental feedback device is selected, the
frequency converter automatically adjusts the
motor angle offset on the first start after power-
up, or when the motor data is changed.
The frequency converter adjusts the motor angle
offset automatically on the first start after power-
up, or when the motor data is changed no
matter what feedback device is selected. This
means that options Manual and Auto are
identical for the incremental encoder.
The frequency converter adjusts the motor angle
offset automatically on every start, or when the
motor data is changed.
Selecting this option turns the automatic offset
adjustment off.
This option updates parameter 1-41 Motor Angle
Offset automatically when the angle value is 0.
Only for absolute feedback devices. The function
uses rotor detection and then applies DC hold to
make the offset adjustment more accurate.

Application-specific adjustment when running VVC
+
VVC is the most robust control mode. In most situations,
it provides optimum performance without further
adjustments. Run a complete AMA for best performance.
Application-specific adjustment when running flux
Flux control principle is the preferred control principle for
optimum shaft performance in dynamic applications.
Perform an AMA since this control mode requires precise
motor data. Depending on the application, further
adjustments may be required.
See Table 3.3 for application-related recommendations.
