2 / 48 page  TMC4210 DATASHEET (Rev. 1.03 / 2015-JUN-03) 2 www.trinamic.com APPLICATION EXAMPLE: RELIABLE CONTROL USING STEP/DIR The TMC4210 scores with its autonomous handling of all real time critical tasks. By offloading the motion control function to the TMC4210, the stepper motor can be operated reliably with very little demand for service from the microcontroller. Software only needs to send target positions, and the TMC4210 generates precisely timed step pulses by hardware. Parameters for the motor can be changed on the fly while software retains full control. This way, high precision and reliable operation is achieved while costs are kept down.

The board features USB and CAN interfaces for communication with control software running on a PC. The power MOSFETs of the TMC2660 support drive currents up to 2.8A RMS at 29V. The control software provides a user-friendly GUI for setting control parameters and visualizing the dynamic response of the motor. TMC2660 |
