6.2.3.5.3 Rotor position detection mode cvv with check
This mode is an extension of the previous mode, which can be used only at opera-
tion with encoder.
dd02 to dd04 have the same function as described above.
In order to check the counting direction of the encoder system, the voltage vector is
electrical turned about 60° in both directions. The rotor must return min. one rota-
tion about 12° via the encoder system. Otherwise an error is triggered.
At high cogging torque the rotor often goes into the desired position with a residual
error. This error is partly corrected in this mode.
