HQ-SXPWM-A 110V spindle power supply

I have an HQ-SXPWM-A 110V spindle power supply in the OX I’m building. It turns on but always runs the spindle regardless of enable or voltage range input. Information on this unit is hard to find, and I have no instructions beyond what I found on aliexpress:

ing current is too large

  1. With flexible multi-function interface

With it powering the spindle regardless of the enable setting or any input settings, I’m worried that I have a dud. I guess I can just run the spindle at full speed (or whatever speed it is actually going) for now…

It’s providing 155V to this 110V-rated spindle. Probably not doing the brushes any favors. Pushing the switches through the case with a bit of plastic, it’s clearly set for 110V and 8A; the default settings. So I think it’s dead inside somewhere.

What’s spindle are you connecting this to?

600W air-cooled; it’s intended as a set (got it from Brandon in his going-out-of-business sale) and used to be sold a lot that way. But most of the hits I see online for the HQ-SXPWM-A controller about how it dies young, and some for the 600W spindle complain about it tearing up brushes and armatures quickly, so I’m wondering about maybe cutting my losses.

I could probably get something like this and get started with the existing spindle without a big investment:

I have extra conductors in the drag chain, so I could move to brushless instead. A lot of those are ER8 though, and I’m all stocked up on ER11. Some of the ER11 brushless spindles have only + and - so maybe they have an integral ESC?
