Infineon Speed Circuit

[philf]

I'm just wondering if anyone is actually USING the supplied speed output line on the Infineon controller (the lone blue wire).

I ask, as I was looking at the smaller (36V 350W) controller and recognizing that the missing functionality is easily added to it (the pads are there - just missing 2 resistors and a transistor). However, in looking at how the circuit was set up on the larger (both the 72V and 48V) Infineons, I couldn't help but feeling that someone goofed. There is an afterthought jumper added to the back of the board to provide 5V to the the output section, but the result isn't what one would expect.

For reference, here are the top and bottom of the board:

I've diagramed the resulting circuit, and it looks like this as wired...

That looks pretty goofy to me. I would have EXPECTED this...

Is it just me?

Lone blue wire is essential for using the CA. Gosh

This is essential for using the CA!

EXACTLY!

Hence my question - does it actually WORK as shipped? Asking that little transistor to try to sink the entire 5V bus in an attempt to pull the speed line low looks a bit futile. Might create a bit of noise, though...

OK! I guess I have ANGER issues maybe?

ALL RIGHT! I NEED GLASSES (The ones in the avatar are safety glasses).

The "jumper" isn't a straight wire... It's a tiny 10K resistor.

This changes everything, so you can pretty much disregard this whole thread

Does this help?

Hey ... Same thing! Good Golly!
BTW ... Your Avatar pic is FREAKY!

NEVER!

 

[philf]

Does this help?

Actually, No.

That's just showing R14 and R35 again.

I was referring to THIS (and, weirdly, it's much easier to see in this picture than it is in real life, due to the lighting ):

On the other controller, there's no indication that there's ANYTHING inside the heatshrink - but there is.

Hey! You talkin' to ME?

Actually, if you think the glasses are freaky, you shoulda seen me back in the 70's. :lol:

Hey Dude! Where's My Car! (Oh Yeah ... I'm sitting on it!)

Hey maybe you have a use for the "lil blue wire"?

Master philf ... What you think man?

Yup - that's exactly what I'm talking about (and yes, it will work) - and is the whole point of this thread...

The "blue wire" doesn't exist on the smaller controllers, and it was the process of looking at the circuitry supporting its function on the larger units that gave me pause to consider how it was laid out.

Happily, the pads are present on the small units - just missing two SMD resistors, an SMD transistor, and one regular axial resistor (and, of course, a piece of blue wire).

 

[Knuckles]

(and, of course, a piece of blue wire).

Be sure to let the "Dummies" know that the wire must be BLUE or it won't work!

 

[philf]

You know, there are some days I'd wish I'd used the RED wire, instead

But then you couldn't do this on weekends ...

The "blue wire" doesn't exist on the smaller controllers.

My EB806XC with timestamp of 081218 was eqipped with the blue wire.

Well, now... The board I pictured has a datestamp of 081218, too!

Interestingly, Keywin's pictures on his eBay listings show these controllers WITHOUT the wire, so I wasn't surprised not to see it. The wire would actually be installed by hand, but it looks like the setup at the factory actually has the pick n' place machine set up to populate these components - if it's given the parts

Hello again

The controller from crazyman arrived germany. And now we do not now to connect the brake-light-switch.
He stopp the motor by braking. The engine is a scooter. We have only one wire to connect. This wire has 12 Volt every time by "ON" By braking 0Volt. This wire must stop the motor by braking. Is there something wrong?

Needs the controller from crazyman 12Volt to stop the motor on the lone wire (E-Brake).
The other the other way.

Have you tried (I'm sure) adding the 2 resistor missing and the transistor to see if it work? (I need to install a CA on this 6 fet controller...that didn't have the blue wire, just like you )

Hi,

i have the same problem, is there no one who can confirm that it works if you add the missing smd parts (and the blue wire of corse)

Could we bypass this problem by using a reed contact and setup the CA-DC like the CA-DC with speed sensor

Please help us to fix this problem

Greetings from Germany

Hi,

i added the resistors and the transistor and it does NOT work? grrr.....

Has someone an idea how i can add the speedinfo to my CA-DC? How does the CA-DC with speedsensor work (with reed contacts) ?

Markus

Yes I did it with a little help from ebikes.ca (thanks to them)

I got a KISS (keep it simple and stupid)

WE DO NOT NEED A SPECIAL SPEED IMPULSE FROM THE CONTROLLER !!!

We can use one motor hall sensor, we only must setup the CA "#Poles" value and the "wheel size". I use my Garmin GPS as a reference to set the 2 CA parameters that the speed match.
