1 motor moves to low position when moving quickly from left to right

Using R3 + 7960 bridge. configured with smc3 software. Both motors perform ok. installed AE F1 2022 edition
installed 2018 and 2022 F1 plugin's

Tested axis and everything behaves as expected.

Start the game and car moves as expected. Motors and Hbridge are not heating up. But when I move quickly from left to right and right to left, 1 motor moves to the down or up position and is not reacting anymore.
When I open scm tool the motor gets back to live. The indicators for the motors a both ON and not switched to Off so the motor is not out of its limits. Tried all kind of setting but still one motor stalls when moving the stearing wheel quickly when driving a high speed. in the foro you can see the lever of the motor in the down position when it stalls. Both motors have the same set up. Any idea?

State what kind of power supply you have , and show a screenshot of SMC3 Utils.
I have the same motors and IBT2 bridges at power supply do not hold (2 pieces are already dead) I test powered 12V and have no problems. Try in the power supply with a potentiometer to lower the supply voltage.

I have this power supply 24 volt 25 amp. the config file is atached. I have replaced the 2 BTS bridges, the Potmeters

when I move the steering wheel quickly from left to right and backwards the motor stops and moves to the down possition, see video. But sometimes iis moves to the upper position

the other motor is still working and responding. Have to start smc tool to "reset" the motor that stalled
What is also did is reverse the a0 and a1 and potmeters and then the other motor does the behavior. So what is can rule out is the p meters, the motors itself and the arduino board.

Kp=390 recommended
PWMmin=60 recommended
Clip input=255 recommended

Can you lower the supply voltage ? or try a 12V supply from a car battery for example ?
This should give you an answer as to what is the cause , IBT2 bridges do not like 24V voltage

in this project the author lowered the voltage to 18.5V.

tried lower the voltage, other settings. Same results. ordered a second power supply and testing with an other game. Will share the results asap

Oke i wired motors to separate power supply. Tested with assorto still the same issue. So i now also used another ardiono and bridges nothing works. The weird thing is. When i reverse the motors on the ardiono the other motor turns down. Also when starting swc3 the motors are not in the off position. What can it be? I tried everything i can think of.

Do you have a fan installed that cools the IBT2?
Show a picture of all the electronics.

Oke but why it you change the wiring so that motors are switched the other motor shuts down?

Yes I have. But I can trigger the shutdown in 5 seconds so can it warmth? Also I only need to start scw3 and it starts again. Really strange. I will make photo tomorrow

How can it be faulty hardware? I changed power supply, switched ardiono board. Changed controllers Switched motor 1 and 2. So then the problem occurs on the other engine. Used another p meter. I used all the hardware the 2dof tutorial also uses. Can i not enable a logbook or something so i can see what happens? I can not find if that is possible.

Also i dont excited any limit. the motor will fail just when i steer left and right fast when going fast. I can steer anyside complete at bank angle and nothing happens. Only when steering fast left right left right at high speed the motor stops.

We solved the problem, removed the 7960 H-bridge and replaced it by a SyberTooth 2x32 and it works like nver before. No heating, easy wiring , easy setup and a lot of settings to play with. The great thing is the real time monitoring via the USB connector,
