(1) The Secure Position has only a resolution of 9 bit because only the 9 MSB’s will be copied from OTP to RAM.
(2) The motion direction to SecPos is given by the
(3) Same behavior in case of HW2 float (= lost LIN address). See also
If the LIN communication is lost AND FailSafe = 0 there will be no secure positioning. Depending on SleepEn AMIS-30623 will
enter the STOP state or the SLEEP state. See
If the LIN communication is lost AND FailSafe = 1 a referencing is started using DualPositioning. A negative motion for half the
positioner range is initiated until the stall position is reached. The motion parameters stored in OTP will be used for this. After
this mechanical end position is reached ActPos will be reset to zero. The direction of the motion is given by the

If SecPos[10:0] = 0x400:
no Second Motion will be performed.
Depending on SleepEn AMIS-30623 will enter the STOP state or the SLEEP state. See
If SecPos[10:0] ≠ 0x400:
A second motion to SecPos is performed. The direction is given by SecPos[10] in combination with Shaft. Motion is
done with parameters from OTP.
