180° offset
(hf det./five step)
Depending on the geometry (e.g. slot width) of the mo-
tor, the saturation behaviour can be inverted depend-
ing on the sign of the current Id. The offset must be ac-
tivated in this case.
If the identification is running or completed can be read in dr55.

6.2.3.5.2 Rotor position detection mode cvv only
A voltage vector with constant electrical position is output in this mode. The
amount of the current final value is adjusted dd02, the ramp time for current build-
up is adjusted with dd03.
If the rotor can freely rotate, it will rotate to a fixed electrical position. The "rotor de-
tection current" flow time is defined with dd04 before the position is considered to
be valid. The required waiting period depends mainly on the vibration of the rotor
after position change.
This procedure is not suitable for IPM motors or when using a holding brake!
Alignment current in % of the rated motor current
Time for the current build-up in ms
Time, when the alignment current is active
(= motor alignment time + decay time of the vibration
caused by the alignment)
Current stiff could not be executed
