hello

i have baldor drive id15h407e

http://www.baldor.com/products/deta...l+Families|tbl_ACControls&product=AC+Controls

at a day the circuit had been fried

the problem in component , it's name RT1 , and i don't know what is this component and what is do ??

i need it's circuit diagram or what is the mean of RT1

i will give who will answer me 10$ by cashu or any other payment transction

thank you

 

For the other helpers on this site, I did the part about looking at all the published information and found nothing about RT1.

 

thank you #12 for your reply

try to search again you may find new thing

 

Is there anything left of it that a picture would describe it?
Schematics like this are usually proprietary.
Could be a thermistor?

Max is asking for a photo of the RT1 part.

 

here some info about it

Yes we know its Baldor VFD but even with the installation manual, they don't show usually show components, unless they happen to be external accessories.

thank you for your help max

 

No component side close up?
Two soldered connections don't tell much of a story?

Max.

i don't know what is this meaning ??

 

The arrow appears to point to a component that either has been removed or is on the other side of the board?
Max.

 

yes it has been removed

because it's frying

from my search i found this

it may be relay

A relay has more than 2 connections.
You can not expect us to tell you what a part is after showing us a picture of it not being in the picture.

 

ok i will try tommorow to get more pictures

thank you for help

RT1 in that form factor is most likely a thermistor (maybe RT means Resistor Thermistor?) and since the circuit seems to be a higher current area it is probably a PTC type to save components from current inrush or motor start current.

If that thermistor is cooked is it likely to be a symptom, not the fault itself (so there is another fault drawing too much current, which then cooked the thermistor).

 

Post a photo of the other side of the board, so we can see RT1.
