iC-MU is an all-in-one, off-axis, magnetic position sensor featur-
fꢈꢃꢄuꢉꢈꢇ
ing integrated Hall sensors with automatic signal conditioning
and processing. The nonius scanning of two magnetic tracks (a
master and a nonius track) is evaluated by two real-time-track-
ing sine-to-digital converters. Following power up and nonius
computation, iC-MU provides incremental encoder quadrature
signals with an index of any count up to 65,536 CPR and an
output at an adjustable minimum edge distance. It also gives
the absolute singleturn position with up to 18 bits per revolution
through various serial interfaces (SSI, BiSS, SPI).

Motor commutation signals for up to 16 pole pairs (U, V, W)
Counter signals and sin/cos signals optionally available
Serial 12-bit multiturn interface
Commutation signals for brushless motors with up to 16 pole
pairs are derived from the absolute position and supplied
through a 3-pin interface. The commutation starting angle can
be preset. External counters can be supplied with pulse signals
for cw and ccw or for step and direction.

Device setup via SPI or I C from external EEPROM

iC-MU captures full revolutions with its embedded 24-bit period
counter and can thus supplement the position data output for
data lengths of up to 38 bits. Optionally, using the multiturn inter-
face the counter can be loaded following a reset by an exter-
nal 12-bit multiturn sensor, for instance. The data is read and
synchronized with the internal position data, and is cyclically
checked during operation. A preset function permits the adjust-
ment of the absolute position after encoder installation.
Operational temperature range of –40°C to 95°C

Besides 2-track nonius computation iC-MU is capable of extend-
ing the rotary or linear absolute position using 3-track nonius

computation. A second iC-MU can be connected up and evalu-
ated using the multiturn interface. In doing so, the length of the
absolute position measurement can be extended.

Besides its automatic signal conditioning functions iC-MU fea-
tures manual compensation of the sine/cosine signal offsets and
phase errors for both channels, allowing it to cope with magnet
errors and encoder assembly inaccuracies.
