It looks like the NEMA rating just has to do with the size of the front or something here is the NEMA 23 one I got. It looks like this is rated 2.8 amps so would you mind I should set my controller dip switches to reflect 2.8 amps right?
Thanks

It's depends on your power supply voltage and what you are driving with the motor. I would start at half of the rated current and see how it works. Yes the NEMA number is the mounting size. What are you driving with your motor?
