The Figure 5 shows the cascading
of the V-bit- Multiplexer of all gear
wheels. The outputs are the 14bits
Gray code in parallel.
The MSB of the complete code is
dependant on the total resolution
of the system. It can be used in steps
of 2 bits (14Bit,12Bit,…etc). Unused
higher bits should be masked to
logical zero.
With the data-multiplexer IC version
of the multi-turn encoder module,
the data multiplexer IC will perform
the complete driving and data
processing of the encoder units
while
constraints.
There is an IC available to combine
both the AEAS-7x00 13/16bit single
turn component and the AEAx-
84AD 12/14bit multiturn module
into one-single powerful multi-turn
absolute encoder. This one-stop
solution enables the design of a
high-end absolute encoder with
minimum component count at
integration level. Figure 6 shows an
application example of integration
of single-turn absolute encoder and
multiturn module using MUIC.
Note:
To simplify the synchronization with single-turn
absolute encoder(e.g. AEAS-7000), the total
solution has been embedded into a single chip -
MUIC. Please refer to the Ordering Information
for this device.
