## Questions & Answers

**Q: The driver says it can be wired ac or dc power, but the directions do not say how to connect dc (+) and (-) to the terminals labeled ac and ac. which one is the (+) terminal?**
A: It's a good question.
On the driver, it show two AC terminals, that meaning you can connect DC+ and DC- to these two AC terminals at random.
Best regards
Daniel Zhang

**Q: I have 1 of these units currently throwing a fault code. Is it resettable or must it be replaced?**
A: I have been through about a dozen of these.  For me if cycling the power did not clear the fault I had to replace the drive.  I know it has to be something simple so I have a box full of them that I "plan" to fix when I have time.

**Q: can this this be used with nema 23 4.0 amp 1.8mh .9ohm ?**
A: yes, of course.

**Q: I see stepperonline also has power supplies.  which one is best for this driver?  i'd like to get one with a vent fan if possible.  thank you.**
A: We are pleasure to recommend you a suitable power supply, but we should know your stepper motor's size and the current.

### ⭐⭐⭐⭐⭐ The "Go-To" Drive for our Stepper-Based Controls
*by S***R on April 25, 2019*

We have used about three dozen of these drives without issue or failure. Amazon Prime is the best source for these drives (price, stock, and speed to get). Our small company builds retrofit controls and rebuilds CNC machinery. We have successfully used these drives on NEMA 23, 34, and 42 motors. For us this drive was a game changer because of the power supply requirements. Nearly every older CNC machine that we come across has a large stepdown transformer in it. Instead of scrapping these transformers and buying or building a custom power supply we simply reuse the old machine transformer to provide 60VAC input. In the few cases where we did not have a spare old transformer we used a 2000 watt power converter (also purchased from Amazon) to step down 120V line voltage to 60VAC.
