So I have just purchased a
NEMA 23 [High Torque Nema 23 CNC Stepper Motor 3.5A 3Nm(425oz.in) 23HS45-3504S], a
Motor Driver [2/4 phase Nema 23 Stepper Motor Driver 24-50VDC 1.5A-4.5A 256 Microstep M542T] and a
Switching Power Supply [Switching Power Supply 100W 24V 4.5A for CNC Router Kits 115V/230V S-100-24]. Below I have attached links where you can find specifications and the data sheets for each. My question concerns the current and voltage I should apply to the NEMA 23.
I am looking for a
high torque (low speed) application, and so speed is not really concern, I care more about accuracy, so I will most likely use larger steps which can retain there intermediate positions with higher precision. Currently the Power Supply is pushing out 24V to the Driver. Here is where I am stuck. The driver has many switches and configurations for the current output. Specifically, it has a full and a half current mode and I am not sure if they are as simple as they seem. If I have the Current Mode Table to Half-Current Mode and the Current Table to 4.5A Peak, does this simply mean that the Motor Driver is pushing out half of 4.5A (2.25A) to the NEMA 23? If so, then would it be safe to switch the driver to Full-Current Mode and send the Motor 3.2A (the motor is rated for 3.5A). I know this may seem like a simple question, but there are always concerns about Back EMF and the like and I would really like to not destroy my NEMA 23 before really using it.
I hope this makes sense and please ask me any questions you may have. Thank you so much for your time!
