iC-MU
MagnetiC off-axis
absolUte position enCoder
iC-MU is an all-in-one, off-axis, magnetic position sensor featur-
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).
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.
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.
