Set current limit - DRV8825 Stepper Motor Driver

Support Motor controllers/drivers and motors

Hi,

I have several of your new high current drivers on order and I need to know how to set the current by measuring the voltage drop over the reference resistor. I have seen instructions for this before (can’t seem to find the link) for other drivers and I will need to know the sense resistor value to be able to calculate the current. (OK, you got me, the forula will help too!)

Thanks in advance!

Hello.

Instructions for setting the current limit are available on the product page; have you looked at that yet?

Please let me know if anything is unclear.

What was unclear was my ability to scroll down the page!
:blush:
I looked at the Resources and FAQ tabs, but never scrolled down. Duh!

Thanks for the response to my stupid question!
