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 trailing edge of the start pulse and the trailing
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 10).
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 – Offset) x Multiplier
Magnet
P =
Magnet
Divisor
P The current position of the magnet in µm
Magnet
R Values for the current position of the magnet
Magnet
in increments (example: result position 1 for
magnet 1)
Offset Offset zero position in increments
Multiplier Length of BTL in μm
Divisor Length of BTL in increments
