Tesla Small Drive Unit Support Thread

[tom91]

We've been ... in a project

Mind sharing the parameters you have been using?

[Jack Bauer]

Same as in the parameter thread.

[tom91]

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!

[Jack Bauer]

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

[Lee Malo]

when I replaced the sensor I took a few pics . This is how the 2 sensors are oriented in that camel snot . lol

Thanks!

Got em in. Should we refill the void in the "camel snot" left from pulling out the old sensors? The new sensors seem pretty secure as is.

Recommend everyone update to the latest software release here :
https://github.com/jsphuebner/stm32-sine/releases
For Tesla use : https://github.com/jsphuebner/stm32-sin ... 2_sine.bin

Also read and try to understand the parameters before powering up :
https://openinverter.org/docs/index.htm ... rs,24.html

A lot of the most common questions have already been answered in the support threads so try the search function first.

Hi all, I notice in V2/3/4 PCBs the following connections are warning as single pin, ie: pin 20 tacho-drive is not longer routed to anything - previously went to an ULN2003ADR

Single pin net ENC_Z_54 on IC1.P$54 at 525.04,466.23
Single pin net SPEED_OUT_25 on IC1.P$25 at 524.04,454.38
Single pin net TACHO_DRIVE on CONN2.20 at 542.92,567.05
Single pin net USER_PWM_62 on IC1.P$62 at 521.04,466.23

Are these functions deprecated and safely ignored?

Thanks all

[Jack Bauer]

Those functions are no longer required on Tesla boards and have been deleted.

[Sparky 61]

Can some please confirm the following, on the TSDU low voltage diagram;
Pin 5 shows forward direction in black is this a positive or negative supply
Pin 12 shows reverse direction in blue is the a positive or negative supply

because on the TSDU 12 volt connection diagram
Pin 5 shows forward direction in red as a positive 12v
pin 12 shows reverse direction in red as a positive 12v

[Sparky 61]

TSDU Brake Pedal Position Sensor, where can i source one of these.

[Jack Bauer]

Direction signals are 12v active high.

[Jack-Lee]

Hi,
a little question... How high i could go with the input DC Voltage? I use 60Ah 300Amax Cells, and i would get the most power out of it

[Lee Malo]

I did a idiot move ! , I played with some setting without saving before What file do I load to reset the parameters ? I feel like an idiot asking this question and sorry to bother you with this NOOB question .

the board is a V4 with the latest software .

[Jack-Lee]

Does anyone know what about the maximum supply voltage?

[Kevin Sharpe]

Does anyone know what about the maximum supply voltage?

AFAIK no one has tested the limits of a small drive unit so I guess 400V is a safe assumption given they use 600V IGBT's in the LDU;

viewtopic.php?f=10&t=76&hilit=tesla+igbt#p515

[Jack-Lee]

Ok, thanks. So it should be ok to usw 100 cells in a row instead of 96

[Kevin Sharpe]

You're going to find out Anything outside of the Tesla default environment is an experiment. If you want to play safe copy what Tesla have done.

[Jack Bauer]

Some good news on board supply. I have now acquired a much more reliable pcb manufacturer here in Ireland and boards will be in stock for immediate dispatch. No more silly delays and boards are being built on an automated smd line so quality is much improved.

[JaniK]

Looking good

[Lee Malo]

I am going cross eyed with looking at this . I am doing something wrong and I have not found my mistake . Could someone point me in the correct direction

After you find out what were the best settings you can post that here for future reference?
https://openinverter.org/wiki/Configuration_Files

I think Damien has that on github?
