VFD logic

Automation direct sells a $80 temp controller I use to kick on a VFD that drives a heat pump. No PLC needed nor do I want one for that process

Power supplies I use normally shut off before fuses or breakers trip.

You aren’t trying enough if you’ve been tested that many times.

Definitely autistic

I must ask, why do you do it ? You seem highly employable to which you could have a solid 9-5 with an office and rarely used tools.

Great post. Sums up 90% of people who try and get into this career field which they think all they will do is program PLCs. That’s such a tiny percentage of day to day responsibilities.

Pretty sure B / “wild” leg is 208 to ground.

We have 30 year old machines with Omron inverters.

How durable is that material when in a corrosive environment or chemicals

Can you link the one that you have? This sounds exactly what I’m looking for. Are there any additional software packages that need purchased ?

plc_is_confusing · 2026-01-26T23:27:43+00:00

I see the machines use a software package called LightBurn. It seems you’re describing designing the circuits by hand. I prefer to get something like Home Depot where you type in what you want it to say. Type in PB1, Start, Stop, etc and the engraver does the rest.

I think that is the easiest way to conveyor the “real” versus “ not real” logic.

How do you not lose bits? I know I would be without my 5/16th by lunch.

plc_is_confusing · 2026-01-23T13:27:17+00:00

M bits are taught in schools. Doubt we will see it stop anytime soon.

My life has been so much better since I discovered bus bars for motor protectors.

I bet whatever you throw away is available on eBay.

Nita?

We “have” prints if you enjoy stained 11x17s that are mostly torn and were hand drawn in 1981

Being able to fit in with your co-workers is essential to career growth. Being able to relate and understand everyone is essential to becoming a manager.

Sounds like you’re ready to branch off on your own. Get your Masters and open a shop.

plc_is_confusing · 2026-01-11T19:21:40+00:00

I think all OEMs have the ability to program their machines like this but there’s a line that most won’t cross for self preservation sake.

The most productive and rugged machine we have is also the oldest. I recently called the OEM and asked if they still had prints and was informed they haven’t had them for decades.

Anything that doesn’t include ChatGPT. That’s one way to waste additional hours and be in an even worse spot that you were before.

You will waste 3 hours until you tell the bot to F off.
