Incremental Interface
The Incremental Interface (IIF) uses an up/down counter of a microcontroller for the angle transmission. The
synchronization is done by the parallel active SSC-Interface. The angle value read out by the SSC-Interface can
be compared with the stored counter value. In case of a non-synchronization, the microcontroller add the
difference to the actual counter value to synchronize the TLE5012 with the microcontroller.
A/B Mode
The phase shift between phase A and B indicates a clockwise (B follows A) or a counterclockwise (A follows B)
rotation of the magnet.
