Practical VFD use for VFD newbies

[MrWhoopee]

This is the one. From the posts in this thread, there are at least 1/2 a dozen of this model in use among members.

In looking thru the parameters, I see P34 "Main rising velocity", for which the default is 25 Hz/S. Could this be the one that controls acceleration on startup? I will likely test this today, but thought I'd ask.

I don't see it. That's too bad. It's a very nice feature on those VFDs that have it. It's not the end of the world though. The VFD and motor will work without it.

It looks like there are a few parameters that might be useful, but only experimentation will determine what they actually do. And a bunch that have no relevance for non-automated control.

But it looks like this model will do the basics just fine.

Am I overthinking this (as is my usual bad habit)?

I really have zero wall space to mount this VFD. I thought I would make a bracket or an arm to attach it to the machine itself (in this case a 22" drill press) but then I thought - will exposing it to vibration be a Bad Thing? Maybe just try to isolate it a bit with some sort of bumpers? Maybe doesn't matter and I'm just being a perfectionist rather than a goodenoughtionist?* Has anyone done this and actually run into problems?

*And ongoing struggle of mine.

I mounted my drill press VFD to the drill press, no issues. i did add a input power on/off switch and some mechanical protection to prevent swarf from entering the case.

I mounted the VFD for my 2X72 grinder in an ammo box right on the grinder. 2 years and still no issues with vibration or dust.
If your drill press vibrates enough to affect it you might have bigger problems.

All of mine are mounted on the machine at a protected location with remote switches. I've never had a problem.

Something to consider though is that all of mine are higher quality ($$$) devices.

I can confirm that P34 does control the startup acceleration rate. I doubled it to 50 Hz/S and the mill starts up more like normal.

Thanks for that!

And thanks all for the feedback.
This is a new-to-me machine and I don't expect more than normal vibration after I'm finished re-assembling it, but as I said, I tend to overthink things.

It seems unlikely that a drill press could generate enough vibration to affect the operation of a VFD.

It seems unlikely that a drill press could generate enough vibration to affect the operation of a VFD.

Drill presses don't generate a lot of vibrations as a general rule. Maybe if it is unbalanced, or if the bit chatters. Drill chatter is high frequency low amplitude vibration. And an unbalanced spindle is low frequency low amplitude vibration. The key part being low amplitude.

Most electronic devices are inherently resistant to this kind of vibration. Even the mechanical ones like relays and solenoids. The mechanical ones are vulnerable to shock. Which is typically tested using the half sign wave method. You can think of it as half of a normal vibration that gets stopped by hitting with a hammer

But solid state electronics are resistant to even this kind of trauma. Sure, eventually, if the blows are hard enough, they will be physically torn apparat, but they won't loose their electric state or malfunction until they get to that kind of distress. Usually the connections fail first. And a CSA or UL acceptable housing is designed to ensure that that is the case

Don’t sweat worrying about your VFD too much. If it’s a shy knees one then hey, it’s cheap.

I know of guys that have used huangyangs for years without issue.

Use it, if it fails, replace it.
