TMC2209 یک آی سی درایور موتور فوق العاده بی صدا برای موتورهای پله ای دو فاز است. پین کردن TMC2209 با تعدادی از درایورهای قدیمی و همچنین با TMC2208 سازگار است. عملکرد بی صدا، حداکثر راندمان و بهترین گشتاور موتور را تضمین می کند. تنظیم جریان سریع و ترکیب اختیاری آن با SpreadCycle امکان حرکت بسیار پویا را در حین اضافه کردن فراهم می کند. StallGuard برای خانه بدون سنسور. ماسفت های قدرت یکپارچه جریان موتور تا RMS 2A را با ویژگی های حفاظتی و تشخیصی برای عملکرد قوی و قابل اعتماد کنترل می کنند. یک رابط کاربری ساده UART گزینه های تنظیم و کنترل را باز می کند.پیشرفته ترین خانواده درایور موتورهای پله ای STEP/DIR صنایع، طرح ها را به عملکرد بی صدا و دقیق برای راه حل های مقرون به صرفه و بسیار رقابتی ارتقا می دهد.

Product Introduction

The TMC2209 is an ultra-silent motor driver IC for two phase stepper motors. TMC2209 pinning is compatible to a number of legacy drivers as well as to the TMC2208. TRINAMICs sophisticated StealthChop2 chopper ensures noiseless operation,maximum efficiency and best motor torque. Its fast current regulation and optional combination with SpreadCycle allow highly dynamic motion while adding. StallGuard for sensorless homing. The integrated power MOSFETs handle motor currents up to 2A RMS with protection and diagnostic features for robust and reliable operation. A simple to use UART interface opens up tuning and control options. Store application tuning to OTP memory.Industries’ most advanced STEP/DIR stepper motor driver family upgrades designs to noiseless and most precise operation for cost-effective and highly competitive solutions.Step/Dir Drivers for Two-Phase Bipolar Stepper Motors up to 2.8A peak –StealthChop™ for Quiet Movement – UART Interface Option –Sensorless Stall Detection StallGuard4.

Wiring Diagram

Motor Current Setting

Below V2.1

V3.0&3.1

Imax -> Maximum current per phase (Imax = Irms * 1.41)
Irms -> RMS (Root Mean Square) current per phase (Irms = Imax / 1.41)
Vref -> Voltage on Vref pin
Vref = (Irms * 2.5V) / 1.77A = Irms * 1.41 = Imax
Irms = (Vref * 1.77A) / 2.5V = Vref * 0.71
The best way to set the motor current is by measuring the voltage on the Vref pin (0…2.5V) and adjusting the voltage with the potentiometer. The maximum settable motor current is 1.77A RMS (0.11Ohm sense resistors), but the SilentStepSticks can only be used up to 1.2A RMS

Note

Vref measures Gnd and the voltage at the middle of the potentiometer.
Do not connect the motor when measuring the voltage, otherwise it is easy to burn the driver.
Power should be connected when measuring voltage, do not just connect USB power supply.
Please pay special attention to directions!

:Setting Method

V2.1 Hardware Connection

You can use every RS232 serial adapter with 0-5V logic levels (e.g. FTDI-Breakout) and the SilentStepStick Tester/Programmer can be used as connection adapter

Tip

The FYSETC TMC2209V2.1 version has been set with jumpers and theTX and RX pins are lengthened for easy wiring You only need to follow the silk screen to wire and use

V3.0 Hardware Connection

Note

V3.1 Hardware Connection

add CLK pin ，not connect in default，tie to GND via 0R
SPREAD pin is floating. Reserve pull-up and pull-down resistors
Move TX from 3 to 5
UART mode is compatible with F6,S6,SKR series and MKS series motherboards
