Is it correct to assume that the maximum current pot is only necessary for over-volting a stepper motor? For example, if vmot is 12V and the stepper coil is 12 ohms, the maximum current will never exceed 1 amp regardless if the maximum current pot is set to 2 amps because of Ohm’s law.
Hello.
Your understanding about the current drawn for a stepper motor is correct. If you want to use the driver that way, just be sure to set a current limit that is greater than your motor would want to draw as you mentioned.
