INFO
The TMCM-302 is a triple axis stepper motor controller module
for external power drivers with step / direction interface. With
its very small size it is dedicated to embedded applications,
where de-centralized high power drivers are desired. The board
can be connected to a baseboard or customized electronics
with a pin connector. The TMCM-302 comes with the PC based
software development environment TMCL-IDE for the Trinamic
Motion Control Language (TMCL). Using predefined TMCL high
level commands like „move to position“ or „constant rotation“
ELECTRICAL
DATA
• 5V DC logic supply voltage
• TTL / CMOS step / direction outputs
• step / direction drivers
(e.g. TMC401, TMCM-013, TMCM-023,
TMCM-078, IDX7505 or TMCM-171)
• UART (RS-232, RS-485) or
CAN 2.0b host interface
• inputs for reference and stop switches
• general purpose analog and digital I/Os
• three motion controllers
for high step frequency
• memory for 2048 TMCL commands
• automatic ramp generation in hardware
• on the fly alteration of motion parameters
(e.g. position, velocity, acceleration)
• high dynamics:
step frequencies up to 300kHz
• 1.8µs step pulse length
and step to direction delay

INTERFACE
FEATURES
rapid and fast development of motion control applications is
guaranteed. The TMCM-302 can be controlled via the serial UART
interface (e.g. using a RS-232 or RS-485 level shifter) or via CAN.
Communication traffic is kept very low since all time critical
operations, e.g. ramp calculation, are performed on board.
The TMCL operations can be stored in the on board EEPROM
for stand-alone operation. The firmware of the module can be
updated via the serial interface.
SOFTWARE
• stand-alone operation using TMCL
or remote controlled operation
• PC-based application development
