Zero Motorcycles Forum | 2013+ / Re: DS 2021 CAN using DVT software
« on: March 23, 2023, 05:17:18 AM »
I finally have it running again.  Thanks to rgutt for the DCF and a lot of time replying to emails.  His bike was the same year so very similar but just a bigger motor and controller.
After putting some settings back in the contactor wasn't engaging.
The CANbus signal from the Sevcon to the MBB was working to tell it to close.
It seemed that the Sevcon was only precharging to 50V and then cut out because of a critical supply voltage.
I found there was a range error on the encoder voltages that was causing a delay in the precharge and by this time the MBB had already turned off the Sevcom power.  4 sec later the power would turn back on and the cycle repeat.

Hey,
here's roughly what I have in my bike. It's not my actual bike but a different Sevcon inverter flashed with my DCF, but the settings are all the same, since it is my bike's DCF.
Hope it helps some. This is a 2013 though (with software update around 2016). So if yours is configured differently, that doesn't indicate anything really


Thanks.  I have found a few problems particularly with the inputs.  A lot of the settings seem ok.  Still not working though.

Thanks rgutt.  I wish I'd known I could just rotate by hand.  Too late now though.
I need to wait 2 weeks before the Zero dealer can look at it.
It is in operational.
What I did was select torque mode and it asked to load default values and I selected yes.  I don't think is has wiped all settings from the sevcon.  There are lots of speeds ant voltages that look like they could be correct.  I can't see how it controls the contactor.  Can anyone describe this?  There is one digital output set for the contactor.  I tried adding 3 in case that was wiped but makes no difference.
If anyone can send me their settings or screenshots it would be greatly appreciated.

I found that I had another unmarked ODB2 style plug too.  I could connect to the sevcon through it.
I noticed the angle was showing as 0° so maybe this setting got lost.  It seems strange the bike was working perfectly but after a week at home while I was on holiday it started misbehaving.
I can adjust the angle through it fine but my software didn't seem to have an option to run the motor and get the plot to work out the angle correction.
I tried using the throttle with limited success.  I seem to have wiped some settings trying and now the contactor won't engage.
Looks like I need to make a 200 mile round trip to the dealer to drop off and another to collect which is what I was trying to avoid in the first place.

I understand Karl.  The 2016 diagram on zeromanual.com shows the same at yours.
I meant maybe a serial command can be sent to the MBB to allow the Sevcon controller to be accessed over the OBD CAN bus.  Or possibly a CAN command to do the same.  As in some kind of service mode.  I would assume that Zero dealers must do this to carry out the "motor commissioning" with the DVT software.

Thanks.  There is a CAN bus on it.  On the diagram it goes straight to MBB2.  I have cleared a fault using it before and I would guess it must be possible to use it when servicing to align the encoder.  Maybe sending the right command to the UART it will connect this to the Sevcon CAN bus.

I am losing power at full throttle so hoping the encoder alignment will sort it.
Bought the IXXAT 1.6 interface and made up an OBD2 lead.  Downloaded the old software but won't connect.
No data packets showing on the canbus.  Tried all speeds.
I put a scope on the can high and low pins and both just at 2.5v with no activity.
Plugged the interface into my car and straight away flashing light and plenty of data so the interface and software are working.
Is there something I need to do to access the sevcom canbus?  I can't see any info on turning on the ODB2 can messages.

If anyone needs the interface the seller I bought from as listed another on ebay for £150.  After a £100 offer I accepted a £120 counter offer.

I insured my new DS last June with Devitt (on Compare the Market) for £220.  That was the day before the policy started because I didn't get the reg no until then.
