BLOCK DIAGRAM TRINAMIC Motion Control GmbH & Co. KG Hamburg, Germany TMC260C and TMC261C DATASHEET (Rev. 1.01 / 2020-AUG-11) 2 APPLICATION EXAMPLES: SMALL SIZE BEST PERFORMANCE The TMC260 and the TMC261 score with power density, integrated power MOSFETs, and a versatility that covers a wide spectrum of applications and motor sizes, all while keeping costs down. Extensive support at the chips, board, and software levels enables rapid design cycles and fast time-to-market with competitive products. High energy efficiency from TRINAMICs CoolStep technology delivers further cost savings in related systems such as power supplies and cooling. TMCM-6110 FOR UP TO 6 STEPPER MOTORS The TMCM-6110 is a compact stepper motor controller / driver standalone board. It supports up to 6 bipolar stepper motors with up to 1.1A RMS coil current. The TMC260 has been tested successfully for 2A peak (1,4A RMS) on this module. The TMCM-6110 features an embedded microcontroller with USB, CAN and RS485 interfaces for communication. All cooling requirements are satisfied by Layout for up to six stepper motors passive convection cooling. TMC429+TMC26X EVAL EVALUATION & DEVELOPMENT PLATFORM This evaluation board is a development platform for applications based on the TMC260, TMC261, and TMC262. Supply voltages are 8 40V DC (TMC260) and 8 60V DC (TMC261 and TMC262). The board features an embedded microcontroller with USB and RS232 interfaces for communication. The control software provides a user-friendly GUI for setting control parameters and visualizing the dynamic Layout for Evaluation responses of the motors. Motor movements can be controlled through the step/direction interface using inputs from an external source or signals generated by the TMC429 motion controller acting as a step generator.
