MODULES F O R S T E P P E R M O T O R S M O D U LES TMCM- 3 23 3-Ax is Enco der Inte rfac e with SPI 1 0 mm M A IN CH A R AC T ER IS T IC S INFO The TMCM-323 is a triple axis encoder interface module. It ELECTRICAL DATA extends the three-axis motion control modules for closed loop • two or three channel encoders (differential or TTL/CMOS) INTERFACE • SPI to host processor 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 • 5V DC logic supply voltage SUPPORTED ENCODERS FEATURES interfaces the 3-axis TMCM modules TMCM-301, TMCM-302 or TMCM-303 via SPI. The TMCM-323 contains three real time coun- • resolution option adapts encoder resolution to motor microstep resolution in fast hardware • extends TMCM-301, TMCM-302 or TMCM-303 for position feedback (already integrated in the operating system) ters for the incremental encoders so that the actual position data is available without software timing problems. • encoder frequencies up to 4M count/s • N-channel event can snapshoot encoder counter • 24 bit encoder counter resolution SOFTWARE OTHER • no additional SW required • 68 pin connector carries all signals • RoHS compliant • size: 80 x 50 mm² SPI Encoder Motor ABN 5V DC Encoder Interface with TMC423 ABN e.g. TMCM-301 Encoder Motor Encoder Motor ABN or TMCM-302 or TMCM-323 OR DE R C O DE D E SC R I P T IO N TMCM-323 (-option) 3-axis Encoder Related products: BB-323 TMCM-303 OP TI O NS H Horizontal pin connector (standard) V Vertical pin connector (on request) www.trinamic.com – for detailed information and datasheets 39
