is it possible to use my KS42STH40-1204A to DM542 stepper driver?
I would use a 24 volt, 2 Amp power supply.

Yes
The operating voltage of dm542 is 20-50v while the standard voltage of the stepper is 2v. does that not damage the stepper or overheat?
Steppers can handle voltages much higher than their rated voltage as long as the current is regulated and kept close to the motor rated current, that is what the driver does.
Your motor has a rated current of 1.2A.
The DM542 has two current limit settings that are close, 1.04A and 1.36A. Both will work. The higher one will provide more torque but the motor will get a little hotter.
thanks, I appreciate your reply!
You are welcome.
Have a nice day!
Hello JCA34F, what power supply would you recommend to power 5x DM542 stepper driver
what would you recommend?
Well if you use the 1.36A setting on the DM542 then the total current for both motor phases will be 2 x 1.36A. = 2.72A. For 5 motors it will be 2.72A x 5 = 13.6A. Let's give a safety margin of about 10%, so that's will give about 15A.
So I would by a 24V supply with a current rating of 15A or more.
