It is designed for high volume automotive as well as for demanding industrial motion control applications. The TMC4210 receives target values for velocity, acceleration, and positioning from the microcontroller and calculates autonomously step and direction signals for the stepper motor driver IC. The motion controller is equipped with an SPI host interface with easy-to-use protocol and with a Step/Dir interface for addressing the stepper motor driver chip. 1.1 Key Concepts The TMC4210 realizes real time critical tasks autonomously and guarantees for a robust and reliable drive. These following features contribute toward greater precision, greater efficiency, higher reliability, and smoother motion in many stepper motor applications. Interfacing The TMC4210 provides an SPI interface for communication with the user CPU and a Step/Dir interface for driver interfacing. Positioning The TMC4210 operates the motor based on user specified target positions and velocities. Modify all motion target parameters on-the-fly during motion. Programming Every parameter can be changed at any time. The uniform access to any TMC4210 register simplifies application programming. A read-back option for all internal registers is available. Microstepping Based on internal position counters the TMC4210 performs up to ±223 (micro)steps completely independent from the microcontroller. Via STEP/DIR signals any microstep resolution can be realized as supported by the driver. |
