TMCM-323 is obsolete and not recommended for new designs. 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, TMCM-303/SG, TMCM-341, TMCM-342 and TMCM-343 via SPI. The TMCM-323 contains three real time counters for the incremental encoders so that the actual position data is available without software timing problems. Applications * Encoder interface for three-axis motion control modules * Provides encoder interface for TMCM-301, TMCM-302 and TMCM-303 * Resolution option adepts encoder resolution to motor microstep resolution in fast hardware * Extends TMCM-301, TMCM-302 or TMCM-303 for position feedback * Encoder frequencies up to 4M count/s * Interface: SPI to host processor * N-channel event can snapshoot encoder counter * 24 bit encoder counter resolution * Encoder interface chip: TMC423 * no additional software required
