Thanks a lot guys, it worked !
It appears that the bug with 'speedkp' is not fixed. I did put it to 1 and it worked perfectly. The car is totaly different now.

Excellent Even I didn't know about that.

A gotya Johannes found out after at Zero-EV we had the same issue and went to the source for help.

Hi,
i have a SDU and installed a Controller von Damien.
Sadly the documentation is not realy "Noob-Friendly". Is there a Parameter-Setup for the "first Start" ? I dont want to kill the Inverter on first try.

Thx

Hi,
I think there is a parameter file on the SDU repository on Damian github. It's called driftparams.json if i'm not mistaken.

Furthermore, can ask my boss if he is willing to share the parameters that we use.

Firstly, if you purchased the board from me it will come with parameters loaded. If not here is the set I use :

Hi,
Patrick Hagemann here
About two months ago I bought a board from you (built up and tested).
The values for maximum current etc. are set to 5000A, so I was careful if the other parameters are correct.

Thx for the help.

The current sensor used on the small drive unit is the Melexis MLX91209.

The 7.3mV/mT version.

Hi Guys
New here and not sure if there is diagram for the front and rear small drive controller plug wires.

Thanks in advance Conrad

Does this help?

When replacing a current sensor does it need to be programed ? The manufacturer states the sensor is programmable . Is the current sensor a drop in and solder or does it need to be programed ? Here is a link to Mouser stating it is programable - https://www.mouser.com/ProductDetail/Me ... DN4jl%2Fc=

I'ts drop in, just make sure you have it in the correct orientation.

Are both current sensors oriented the same way ?

They do not need programming and yes they both go in the same way.

Cheers mate

What contactor and pre are everyone using?

Cheers Conrad

Thanks mate

Does anyone have a link for a contactor and fuse supplier for one of these.

Cheers CG

So a quick announcement on board pricing and lead times. Of late I have been experiencing untold problems with delays and quality from my pcb builder. Some customers have been waiting months for boards which is unacceptable. I have been working to resolve this and am pleased to announce that I have a new pcb maker signed up. Boards will be machine assembled and undergo AOI. This will let me have boards in stock almost all the time reducing lead times to a matter of days and resolving a lot of quality problems. Bad news is a slight price increase on drive unit boards from 500 to 600 euros for built and tested. Bare pcb pricing remains the same.

I wonder if anyone knows the size of bolts for the small driveunits to fit each of the motorbrackets?

We've been running some tests on the VW Bus project (here) using a ~200V Toyota Prius battery. The integrated contactors, pre-charge components, and safety disconnect make this a recommended test tool for anyone using the SDU in a project

Mind sharing the parameters you have been using?

Same as in the parameter thread.

No compensation for the voltage? Makes the drive unit quite laggy down low.

Just busted my current sensor and if you can't tell from my question then I'll say it explicitly. I'm a noob.

My replacement current sensors will be getting here in a couple of days. Do I just pull out the old sensors from the "goo" and drop the new ones in? or is there something more involved?

Thanks!

Yes they go back into the goo. Just be aware of the orientation mark on the device.
