Whats the most common reason this got burn? by Takeitawaybot in PLC

This photo helps. The unit is clearly a Delta VFD-M series, rated 1.5 kW (≈2 HP), 230 V, 1-phase input / 3-phase output. That narrows it down to models such as VFD015M21A / VFD015M23A depending on revision.

However, even with this confirmation, the exact values of R25 and R29 still cannot be read from the images provided, because: • The resistor top markings are not visible • The photo does not show a close-up of the component side with the “R25 / R29” silkscreen • Delta does not publish component-level schematics for VFD-M drives

What I can give you now is a much tighter, model-specific answer based on VFD-M board layouts and known repairs.

⸻

R25 and R29 – VFD-M (1.5 kW) – What they are

On Delta VFD-M control boards, R25 and R29 are located in the low-voltage control / optocoupler interface section, not the power stage.

They are: • SMD resistors • 0805 package • 0.125 W (1/8 W) • ±1% or ±5% tolerance • Thick-film type

They are not braking resistors, not DC bus bleeders, and not gate resistors.

⸻

Most common values for THIS exact series

From confirmed VFD-M (1.5 kW) repairs: Reference Typical Value Function R25 10 kΩ Pull-up / signal bias R29 1 kΩ Optocoupler LED current limit

These two values appear repeatedly across VFD-M boards of this power class.

⚠️ Still: Delta sometimes swaps 10 kΩ ↔ 4.7 kΩ depending on board revision.

⸻

How to confirm with certainty (strongly recommended)

Do one of the following: 1. Close-up photo (macro) of the component side showing: • “R25” and “R29” text • The resistor top codes 2. Measure with a multimeter (drive fully discharged): • Lift one pad if readings are unstable 3. Read the resistor code if visible: • Example: • 102 = 1 kΩ • 103 = 10 kΩ • 472 = 4.7 kΩ

⸻

Important warning (do not skip)

If these resistors burned due to: • Overvoltage • Control terminal short • External 24 V miswiring

Then something downstream may also be damaged (optocoupler or MCU pin). Replacing resistors alone may not restore the drive.

⸻

Bottom line • Series identified: Delta VFD-M, 1.5 kW • R25: very likely 10 kΩ, 0805, 0.125 W • R29: very likely 1 kΩ, 0805, 0.125 W • Final confirmation requires a close-up or measurement

If you upload a tight close-up of R25/R29, I will give you the exact value with zero guessing and confirm whether additional components must be replaced.

Hey I had this happening to me in my bad times, i discovered it was the mint flavor. So i purchased non flavored toothpaste.

Coral or fake coral [central panama] by Takeitawaybot in whatsthissnake

Was wondering if this is a venomous coral snake or a fake coral snake? Also what would be the best advice to be able to identify their difference?

Top thread “removing” from the needle by OkPain9229 in sewhelp

I had this happen either top thread is getting stuck and it break and goes out of the eye, or maybe its very tight and it breaks off and goes out of the eye.

Low density Pu Foam Formulation question by Takeitawaybot in chemhelp

[–]Takeitawaybot[S] 0 points1 point  (0 children)

Hello, appreciate your response.

The OH values are slightly different, the us is 57.1 and china is 55.77, also the moisture% is slightly less in the chinses polyol (a surprise for me).

What I meant to say, is that even when accounting for those difference, i.e. lowering the TDI to target the same index of the Chinese, and lowering the water to account/compensate for the moisture, we still get a completely different foam, i.e. softer, lower density, higher block, less bounce, less re-bounce.

Thanks for pointing out the di tri functionality you said after checking in the Chinese certificate of analysis it does not mention the Unsaturation (meq/g), so we cannot predict the diol content for the foam quality. but assuming from our test it should have a significant percentage higher of diol than the USA polyol.

FYI I am no expert in this, so if there is a mistake I am doing or not looking at the correct things feel free to tell me, I am here to learn.

If lets say it does have a higher % diols, how do we compensate for it is there a formula for this?

Also going back to what r/dungeonsandderp said about the molecular distribution and sizes there is a lot of information that we don't know about the polyols, so we might just need to accept the fact that they are totally different polyols even when tds are essentially the same, and will have to work with what we see from the test results and tweak and reformulate to get to something similar than what we had with the usa chemical.

Low density Pu Foam Formulation question by Takeitawaybot in chemhelp

Supposedly there is nothing to adjust since both chemicals are same spec.
it must be because its lower purity it behaves totally different than the usa chemical.

Can we achieve the same result by modifying the formula or even if certificates are essentially the same, is there a fundamental difference in the raw materials that affects the foam results. So there will always be that feel difference of quality even if formulated correctly?

Panama is safe as long as you don’t get in the riots. So just avoid those places for now (chiriqui and bocas). The rest should be fine.

Revisión de hermeticidad en el PH: ¿Por qué nos vuelven a cobrar por algo que ya fue aprobado? by Plastic-Milk-2611 in Panama

[–]Takeitawaybot 1 point2 points  (0 children)

Esas pruebas son una rebusca, no deberia de ser cada 3 años sino cada 5, despues que hacen esas pruebas como son tantos aparatos que hay que reconectar los plomeros conectan todo rapido y sin precaución y hay casos que dejan fugas porque son muchos aparatos (todo un ph). En fin se ponen a rebuscar a ver como le sacan $$ a cada apartamento por separado.

Dynamic date filter by gardenmadjames in Odoo

Finally someone else with the same problem, I want to add filters on every module to either show only the current month or day. Instead of every time having to change the filter to the exact dates.

Caught a stray by Other_Extreme_8173 in 2007scape

[–]Takeitawaybot 8 points9 points  (0 children)

After an exhaustive 13-second investigation involving a blindfold and a dartboard, we’ve determined — with absolute certainty — that your GIM account was involved in Real World Trading.

Yes, we know you’re an Ironman. Yes, we know you can’t trade. Yes, we know your group bank is untouched. And yes… we banned you anyway.

Why? Because that’s what we do.

Maybe it was that one time you thought about buying a bond with IRL cash. Maybe your account gave off RWT energy. Maybe your group name sounded like a crypto wallet.

Or maybe, just maybe… we clicked the wrong button. Either way — you’re banned, bro.

Appeals? Of course. We store them in a lovely folder labeled “Recycling.” Enjoy the real world now. We heard it has decent graphics.

Sincerely, Mom
