Ive been working on a project and started setting up the wiring for a NEMA 17 Motor. I read that the Pololu DRV8825 needs to be adjusted for the rated current of the stepper motor. I watched the video but was confused what to set the current limit to if the stepper motor phase current is higher than the continuous current per phase. Below are the specs of the motor and the driver:
[u]NEMA 17[/u] Step Angle: 1.8 Peak Current is 1.68A/phase 4 Wire Bi-Polar 12-24VDC (Recommended)
[u]DRV8825[/u] Minimum operating voltage: 8.2 V Maximum operating voltage: 45 V Continuous current per phase: 1.5 A1 Maximum current per phase: 2.2 A2 Minimum logic voltage: 2.5 V Maximum logic voltage: 5.25 V
From watching the video on the Pololu website would I set the driver to a limit current of 1.68A? Meaning the VREF should be 0.84 V?
Thanks again guys!
