AD2S1210 LOT indicate

Hi all,


In the datasheet 17 page at AD2s1210, 

Loss of Position Tracking Detection

LOT can be indicated for step changes in position (such as after a RESET signal is applied to the AD2S1210).
It is also useful as a built-in test to indicate that the tracking converter is functioning properly.


What does it means,  "for step changes in position" ?

As in the following, if the resolver indicates the LOT every step rotation, with every no latch ?


           0°→30°→-30°→0°→60°→... continue

LOT indicate↑  ↑     ↑        ↑     


Best regards,
