Zombieverter VCU <> Outlander RWD <> ISA IVT-S

[student]

Hello,

I need help getting my Outlander Rear Inverter running under zombieverter.

I couldn't get it running on version 2.22a, so I updated zombieverter to version 2.30a, which didn't work.
Connecting a different inverter also didn't work.

Parameters INVudc, tmphs, tmppm the receive stably from inverter.

The resistance between CAN H and CAN L is 59 ohms. The resistance on the ISA and zombieverter is 120 ohms.

I probably missed something important.

I can't figure out how to attach a file.

P.S. I apologize for any inaccuracies; I'm communicating via Google Translate.

Hello and welcome.
You will have to add more context. Pictures, parameter file all that helps that we see the same as you

[student]

Thank you very much.
Apparently, I couldn't attach files without the administrator reviewing my first message.

We need wiring info and pictures of your setup.

And info on the steps you have taken. Like setup your throttle, plot your pot and potnom ect.

Hello there. You managed to get into RUN mode, so your IVT Please clarify. Is this the resistance when there is 12v applied to the system (I/e it is on) or when it is disconnected (I/e it is off)?

Resistance test for CANBUS only works when there is no power. If, with power off, resistance is 120ohm, you only have one working resistor. If it's 60ohm, you have two resistors (good). 40ohm means too many resistors (3). 0ohm means there is a short on the line.

Perhaps you have not set up your CAN network correctly? The two resistors need to be at the ends of the main line. This can be quite long. Any offshoots from the main line should be less than 30cm ideally.

My test set up (Zombie, Outlander RDU, IVT) runs fine on 2.30.

When I was setting up my test circuit, I also had an issue where the IVT shunt worked well enough to send the Zombie data to allow recharge to successfully complete and enter RUN mode, but the Outlander inverter didn't work. In that instance, I was actually missing a terminating resistor (I thought the Zombie had one but it did not). Adding the resistor fixed it.

When I had issues, I posted a similar message. The replies and my documented solution may be helpful to you.

Edit: forgot to post the link

Yes, of course, I took measurements without power.

59 ohms is the total resistance in the CAN line.

It was after reading your thread that I checked my CAN line.

Other things to check are:

1. Is the inverter getting enough power? I found that I needed to use a bench power supply rather than a 12v battery, and to actually use relays to get 12v to the inverter for it to operate correctly. Having good 12v connections, this enough wires is a must to avoid voltage sag.
2. Are the can line branches short enough?

INVudc, tmphs, tmppm the receive stably from inverter.

Good, and pictures shows also udc and power values so CANbus should be fine to both inverter and shunt.

When you press throttle, pot and pot2 are getting higher, right? And how about potnom and torque, does those change value too?

My test set up (Zombie, Outlander RDU, IVT) runs fine on 2.30.

Could you post your settings file for version 2.30a.
I'll try to compare the settings; I might have made a mistake somewhere.

All of these look good to us.

Please show your wiring of the inverter to motor and the HV wiring.

Thank you. I started drawing a connection diagram and checking the necessary signals on the inverter contacts. It turned out that I had mistakenly connected the +12 volts to the RSDN.

Now everything is fine, the motor started to rotate.

Note that RSDN should be pulled low.
