Features
The TMCM-342 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 centralized
or de-centralized high power drivers are desired. The board can be connected to a baseboard or
customized electronics with a pin connector. The TMCM-342 comes with the PC based software
development environment TMCL-IDE. Using predefined TMCL (Trinamic Motion Control Language) high
level commands like “move to position” or “constant rotation” rapid and fast development of motion
control applications is guaranteed. The TMCM-342 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 onboard EEPROM for stand-alone operation. The firmware of the module can be updated
via the serial interface as well as via the CAN interface.
Applications
Controller board for control of up to 3 Step / Direction drivers e.g. TMCM-035, TMCM-023 (triple
driver), IDX or PD-013-42 mechatronic module or TMCM-078 step/direction driver
Versatile possibilities of applications in stand alone or host controlled mode
