Overview (continued)
All of the modules have programmable Transducer Setup Parameters that allow you to
scale and adjust the position and tachometer data. Additional Module Setup Parameters define
the type of transducer attached to the module, the digital format of the position and tachometer
data, and how the module communicates this data to the processor. The module can be
configured to use either block or single transfers.
When configured to use block transfers, you can further configure the module to accept
programming instructions and commands over the backplane. With backplane programming
enabled, you can read back parameter values instead of position and tachometer data by
entering Read Status Mode.

The 1730 and 1740 modules covered by this manual are primarily intended for single turn
applications. They can be used in multi-turn applications by placing a gear ratio between the
output shaft of the machine and the transducer. AMCI has a line of transducers with an inter-
nal (x):1 ratio for use in these applications. However, you must remember that the maximum
number of counts remains fixed at either 1,024 or 8,192 counts. If you need higher resolution,
you must use a 1760 module. These modules provide up to 4,096 counts per turn over a
maximum of 180 turns. (737,280 counts max.)
See pg. 1-4, AMCI Compatible Transducers, for more information on the single and multi-
turn transducers available from AMCI for use with the 1730 and 1740 modules.
