INFO
The TMCM-323 is a triple axis encoder interface module. It
extends the three-axis motion control modules for closed loop
operation. With its very small size it is dedicated to embedded
applications. The board can be connected to a baseboard or
to customized electronics with a pin connector. The TMCM-323
interfaces the 3-axis TMCM modules TMCM-301, TMCM-302 or
TMCM-303 via SPI. The TMCM-323 contains three real time coun-
ters for the incremental encoders so that the actual position
data is available without software timing problems.
