Suggestions for tb6560 stepper motor driver

I am working on a project where I need to control a stepper motor. Earlier I was using L298n motor driver. It worked fine until the stepper motor went into hold state. Because it draws maximum current and eventually burns the driver module.
Now I am upgrading my project to a new driver and I searched a lot and found tb6560 stepper motor driver (
https://www.oyostepper.es/category-16-b ... -paso.html ) which is very good. Now I wonder if this problem will occur again with tb6560.
My stepper motor is nema17 stepper motor with 2.8 ohm resistance per coil and the current recommended in the datasheet is 1.4 amps, I don't know why they recommend about 12 volts/2.8 ohms = 4.3 amps per phase. Please guide me about tb6560.
Please reply me as soon as possible!

Yes, the TB6560 is a better choice. Just set the current limit to 1.4A (your motor’s rated current), and you’ll avoid overheating. Use cooling if needed, and enable idle current reduction if available.

Your choice is correct. But remember to set the current limit to 1.4A or lower to protect the motor and driver. Avoid relying solely on Ohm's law—stepper drivers use PWM to regulate current despite the higher voltage. Consider cooling for extended hold states.

The TB6560 is much better suited for steppers, but only if you properly configure the DIP switches for current control. That "12V / 2.8Ω = 4.3A" thing is just theoretical—what really matters is the rated 1.4A from your motor’s datasheet. Always go with the datasheet value unless you enjoy the smell of burnt electronics!

Also double-check your power supply's voltage and current handling, and make sure the TB6560 has a proper heatsink. If set up right, it should handle hold current just fine without burning out.
