openinverter forum

Hi all,

I am trying to get a LS210 gearbox with matching inverter from a GS300H to run on the bench with a Zombieverter.

I have a Zombieverter with a calibrated throttle pedal wired up. I want to use a 60V bench power supply for High Voltage, apparently that's enough to get it to spin.

Now I bought an ISA shunt but I am struggling how to integrate it. In the Wiki about the ISA shunt page it is written that you need to re-program it with an Arduino Due and a CAN shield, yet I found several threads where people are mentioning that you can initialize the ISA shunt via the Zombie Web interface?
I already have a Kvaser Leaf for CAN access, if I could avoid to purchase an Arduino just for a one-time initializing process that would be good.

Yet I could not find instructions how to initialize the ISA shunt via the web interface. Any advice?

thanks!

https://openinverter.org/wiki/ZombieVer ... _ISA_Shunt:

You no longer need to use the Due, Zombie can initialise the Shunt itself.
connect it up correctly ensuring you use the correct connector on the Shunt (this has caught me out in the past), set the zombie to Init on, save params and power cycle both the zombie and shunt, I believe the zombie needs to be powered after the shunt when you turn them back on.

Ensure the shunt CAN is set to the correct pins on the Zombie. Do you have anything else on the CAN bus network? if so, remove it and initialise with only the Zombie and Shunt. There is a video of Damien performing the process, it isn't super detailed in this specific procedure but should help with the basics.

I may have missed out some things but people will be along to correct me if so...

Is the Shunt a terminated or non terminated version?

have you searched the forum?
This might help.

Ah Tom beat me to it. Seems what I wrote isn't 100% correct follow the procedure on the wiki Tom posted and try powering the shunt first after powercycing as mentioned

thank you @Tom91 and @Jacobsmess.
I managed to initialize my ISA shunt, although the namings of the parameters mentioned in the procedure of the "ZombieVerter VCU" Wikipage do not match any more. I assume they changed when the console was updated. If I knew how to edit the Wiki I would update the page and the "Isabellenhütte" Wikipage as well. The information there is obviously outdated as well.

I can see "udc" Voltage reading from my HV-power supply in the console now. Yet I did not get the motor(s) to spin.

As mentioned I use a 60 V / 5 A bench supply as HV-power supply.
I am running Zombie Version 2.22.A. I managed to get the "opmode" into "Run", I switched the "dir" to "Drive" and I see "potnom" value rise when I press the pedal. Yet no spin of the motors.

How to / where to start trouble shooting in this case? Apart from checking correct wiring again, is there anything I can measure on the inverter or on the motor side?

Post your params.

Do you see any info from the inverter? invudc tmphs ect.

Did you wire it up according to the wiki?

Login to the wiki using the same credentials as you use for the forum. Then there wil be an option (a pencil icon I think) to edit the page on the top right. If you scroll down you can also edit specific sections of the page rather than the whole page.

yes I wired it up according to the information I found on the wiki / forum here.

The two resolvers are connected, but temperature sensors from the two motors are not connected, and the parking selector is also not wired. I assume you do not need either to get it to spin.

I have 12 V on the B2 and GRND2 (PIN B/B2 and GRND1/GRND2 are internally connected, so I think wiring one of each is enough)
I have 60V on the HV-input, but "invudc" shows 0V.

The B+ needs to go through the Inverter relay controlled by the zombie.

The Inverter B1 is wired via a relais (controlled by the Zombieverter).
What I meant is that the control via Zombieverter works and I have 12 V on the Inverter.

Okay, show us pictures of all your wiring.

You need inverter comms to work first.

Make sure your inverter casing (and transmission) are also grounded

Here is a diagram of my wiring: as well as a real-life picture: The cables between the two resolvers and the Zombieverter and the inverter to Zombieverter were done with CAT4 communication cables. They are twisted but not shielded. As this is just a bench-application I thought this is enough... yet the cable diameter is quite small and it was a challenge to crimp them. Probably I'll check electrical continuity between the pins again.
Any other advice?

OK, partial success. Found a broken wire / loose contact between Zombieverter and Inverter.
Now the Inverter is up, yet when I press the throttle the motor(s) is only shuddering and doesn't spin.
Could this be due to wrong settings or is my Power supply too weak (5 A at 60 V)?

60v 5a should be sufficient for the motor.

Post logs. Also it can be too little depending on what you are requesting.

Plot InvUDC and potnom

here's two plots.
The Voltage from the power supply collapses drastically when I push the throttle.
Seems the power supply is too weak?

Yes thats it, get some lead acid batteries in series or something. Also it seems to drop alot from the shunt to inverter, you clearly wired it very poorly with unsuitable cables.

Changed my wiring between power supply and inverter to 10mm². That must be more than sufficiant for 5 Amps...

@andybpowell got his l210 to spin with a similar power supply (300 W, same as mine, so I think this should be enough):
viewtopic.php?p=62388#p62388

Tried to get mine to spin after I changed the wiring, still only shuddering. What seems odd to me is that as soon as "potnom"-value changes the voltage drops, but goes up to initial voltage and stays there (if potnom does not change). The voltage drop happens only if potnom / throttle value changes.
Could this be an issue with wrong settings?

I've not looked at your params but Tom suggested the PSU might not be up to the task depending on what you're trying to pull from it. I'd go through the params and dial things back. Turn off regen (if its not already) and turn things down and see if things change.

Also check the reported speed from the inverter and the resolver wiring. Is it shielded resolver wiring? What is the wiring for the motor phases, is it stock?

Checked all wirings, pinning is correct.

Wiring for Motor phases is stock, resolver wiring and communication between Zombie and inverter are twisted but not shielded.

Can I check the signals from the resolver by turning the output shaft by hand? Are there any spot values for that?

Yes, Damien shows this in a video somewhere

Any more hints which video / context this was? Damien published quite some Videos

Hi Tom, could you elaborate how to check the "reported speed from the Inverter"?

Bintang 5 wrote: ↑Thu May 15, 2025 7:29 pm Hi Tom, could you elaborate how to check the "reported speed from the Inverter"?

You can select it on the spot values display, it will then allow you to see the speed on the gauge screen.

Re the video, it's the FOC tuning marathon I think. Not an L210 and not a Zombieverter but I think you should be able to see the resolver position somehow. I may be wrong about this on second thoughts. Others will clarify I'm sure.
