Fig. 6-1: Basic signals for position sensing
Fig. 6-1 displays the basic signals used for position
sensing. The sensing cycle starts with PLL-Sync_out
which generates the start pulse. Measurements are taken
between the falling edge of the start pulse and the falling
edge of the corresponding stop pulse (see Fig. 6-1).
Time T is available in the position result register (see
Magnet
Memory address space mapping on page 11)
The PLL_Sync_out time interval must be
defined by the user during startup.
The position of the magnet can be calculated using the
following formula:
(R
P =
Magnet
P The current position of the magnet in µm
Magnet
R Values for the current position of the magnet

Offset Null position offset in increments
Multiplier Length of BTL in µm
Divisor Length of BTL in increments
