12 BIT ANGULAR HALL ENCODER
Rev B1, Page 2/23
DESCRIPTION
The iC-MH 12-bit angular encoder is a position sen-
sor with integrated Hall sensors for scanning a per-
manent magnet. The signal conditioning unit gen-
erates constant-amplitude sine and cosine voltages
that can be used for angle calculation. The resolu-
tion can be programmed up to a maximum of 4,096
angular increments per rotation.
The integrated serial interface also enables the posi-
tion data to be read out to several networked sensors.
And the integrated memory can be written embedded
in the data protocol.
The incremental interface with the pins A, B and Z
supplies quadrature signals with an edge rate of up
to 8 MHz. Interpolation can be carried out with maxi-
mum resolution at a speed of 120,000 rpm. The po-
sition of the index pulse Z is adjustable.
The commutation interface with the signals U, V and
W provides 120° phase-shifted signals for block com-
mutation. The zero point of the commutation signals
is freely definable in increments of 1.875° over 360°.
The commutation signals are available for EC motors
with 1 and 2 pole pairs.
The RS422-compatible outputs of the incremental
interface and the commutation interface are pro-
grammable in the output current and the slew rate.
In conjunction with a rotating permanent magnet, the
iC-MH module forms a one-chip encoder. The entire
configuration can be stored in the internal parameter
ROM with zapping diodes. The integrated program-
ming algorithm assumes writing of the ROM struc-
ture.
