Information content of the test signal
The "five step“ method uses the saturation of the motor for detection of the rotor
position at standstill.
Five different voltage vectors are applied to the motor within a few ms. The current
level to be reached can be preset via parameter dd02. The position of the rotor can
be deducted by means on the current rise times.
dd02 should be set to the maximum permissible motor current, since higher current
causes higher saturation and thus more precise identification.
If this method can be used for the motor, cannot be calculated previously with the
motor data (Ld,Lq).
dd08 indicates the quality of the information content.
Parameter (dd07) defines the level when an error shall be triggered, because the
information content is not sufficient (a level of 5% should be selected as starting
value).
The information content can be different at different rotor positions. Therefore sev-
eral different electrical positions should be tested at start-up.
