About
|
|||
|
|
-----
|
|||
|
|
|
|||
|
|
The TMC26X is a stepper motor controller for bipolar stepper motors. From the trinamic web site:
|
|||
|
|
|
|||
|
|
The TMC262 is the first energy efficient high current high precision microstepping driver
|
|||
|
|
IC for bipolar stepper motors. The unique high resolution sensorless load detection stallGuard2™
|
|||
|
|
is used to for the world’s first integrated load dependent current control feature called coolStep™.
|
|||
|
|
The ability to read out the load and detect an overload makes the TMC262 an optimum choice for
|
|||
|
|
drives where a high reliability is desired at a low cost. The new patented spreadCycle PWM mixed
|
|||
|
|
decay chopper scheme ensures best zero crossing performance as well as high speed operation.
|
|||
|
|
The TMC262 can be driven with Step & Direction signals as well as by serial SPI™ interface.
|
|||
|
|
Using the microPlyer allows to operate the motor with highest 256 μStep smoothness reducing the
|
|||
|
|
input frequency to 16 μSteps. A full set of protection and diagnostic features makes this device
|
|||
|
|
very rugged. It directly drives external MOSFETs for currents of up to 6A. This way it reaches
|
|||
|
|
highest energy efficiency and allows driving of a high motor current without cooling measures
|
|||
|
|
even at high environment temperatures.
|
|||
|
|
|
|||
|
|
|
|||
|
|
The unique features of the TMC26X are that everything can (and must) be controlled in software:
|
|||
|
|
|
|||
|
|
* the motor current
|
|||
|
|
* microstepping
|
|||
|
|
* stall protection
|
|||
|
|
* current reduction according to load
|
|||
|
|
* stallGuard2™ sensorless load detection
|
|||
|
|
* coolStep™ load dependent current control
|
|||
|
|
* spreadCycle hysteresis PWM chopper
|
|||
|
|
* microPlyer 16-to-256 μStep multiplier
|
|||
|
|
* full protection and diagnostics
|
|||
|
|
|
|||
|
|
This makes the TMC26X a bit harder to use than other stepper motors but much more versatile.
|
|||
|
|
This library resolves all the complicated stuff so that you can use TMC26X straight away.
|
|||
|
|
Furthermore, all the settings are implemented in high level interfaces so that configuring your
|
|||
|
|
motor is a breeze.
