  I was riding into work on my FXS this morning at full throttle at almost max speed when I the bike suddenly slowed.  The best way I can describe it is it felt like a very strong regen (way stronger than what 100% feels like) for a second or so.  I quickly rolled off the throttle and things seemed to go back to normal so I continued riding.  No other issues were experienced on the ride back home this afternoon.  Logs obtained from the online parser are pasted below.  This happened around 7:07 AM as indicated on the dash, so I think something is a little off on the times in the log file.  It was close to the end of my trip, so my best guess is that this happened around 04:53 in the logs.
  Has anyone had an experience like this before, or does anyone see anything unusual in the logs?  I have seen the SEVCON CAN EMCY Frame and Batt Dischg Cur Limited  other places in the logs, so those are not unique to this time.  It looks like there's a big discrepancy between MotAmps and BattAmps, but I'm not that familiar with the logs and don't know if that means anything of significance. 

Any ideas on anything else to look at or check?  The experience was a little unnerving.  It would be nice to know what happened and if it was some kind of isolated incident or something that needs to be looked at for warranty.  Taking it into a dealer would mean renting a trailer and several hours of driving.


Thanks!

didn't see this a couple posts down?   Sudden Braking Followed by No Response on Highway

what year is your bike? 2016? if so this is at least the 2nd case. i would definitely be contacting Zero and sending some logs with a detailed description of the event.

this does not make me happy to hear...

laters,

laramie 

[domingo3]

Yes, it's a 2016.  Sounds like it could be the same thing, but your experience was clearly more severe than mine.    My experience was more like Fred's. Have you gotten any response about this?  Will send logs now. If it is the same thing, I don't think it has anything to do with water.  I haven't ridden in the rain in a few weeks.

[Electric Terry]

This sounds like a ride through fault that is very rare but usually will only happen at full throttle situations where the Sevcon is at the power limits of its current control.  It's nothing to worry too much about.  If you don't like it, switch to custom mode and set max torque to 95% and that should fix it.  You are just at the very edge limit.  In fact you could probably set it to 98% and be ok.  This is just a guess on my part but its what it sounds like to me.  Try that and see.

What's your firmware and board version?

I hope this isn't an indication of something inherently wrong with the FXS.

[Lenny]

Sadly, I have to admit that I already experienced something very similar on my MY16 FXS. Message looks quite similar, I also noticed a sudden drawback of power, but I can't confirm whether I could have ridden on or not, as I turned off and back on immediately. I first thought I might have run into the custom speed limit, but it was set higher. Nevertheless I want to test soon how it feels to get to the customized speed limit.

Apparently, owning a Zero isn't worry free yet.

Lenny were you at full throttle when it happened?  Did you see my comment above?

[Lenny]

Can't remember exactly as this happened already a few days ago and I didn't pull the logs until yesterday. Probably I was, because I just overtook someone and was speeding up even more. Anyway this shouldn't happen, limiting torque by the app is a workaround and not a real solution ;-)

Just found a list with SEVCON error codes. Can't find "46C3" as in our logs, but the "52C3" out of MajorMajor's logs from the other thread is a "current control fault".

[Electric Terry]

Right if you read what I wrote above, current control is exactly what I figured.  Zero could have sold the bike and dialed back power 10% from the factory, but I think they dialed it up to try to give everyone as much power as possible since instances of this happening is so rare, and when it does, it's supposed to self correct.  Called a ride through fault, all you have to do is return the throttle to the off position and it should reset and give acceleration again.  This would happen on my 2012 a lot, maybe 10 times a day, but at the time wasn't a ride through, so would require a key cycle.  Updates later came that made them ride through as well. 

On my 2015 I've never had one, but perhaps on the next bike they should hide some power so it's not on the edge of current control, what do you think?  I personally would say give the user all the power, as a current control fault if it were to ever happen is not the end of the world.  No worse than on my gas bikes hitting condensation drops on hot humid days and cool nights where the fuel line would hit water and lose power for 10 seconds or so until fresh fuel got to the injectors again.

Terry,

  I really appreciate the information that you share with us.  I wish that we could get this kind of stuff officially from Zero rather than relying on 2nd hand information (although I consider you to be pretty reliable).

  I wanted to check with you, though, to make sure we're talking about the same phenomenon.  I know what coasting feels like, and I know what "100%" regen feels like, and this was neither one of those.  There was very significant resistance from the back wheel - several times "100%" regen.  Is this the ride-through fault that you are suggesting?  If so, what is actually happening that causes the resistance? 
  Do you know if this correlates to SEVCON error code 46C3 as Lenny speculated?  I've seen that particular error code in other instances in my logs, but this is the only time something happened that I could sense.

  I am by no means alarmist, but I think that this is dangerous and not something to dismiss as "not the end of the world".  Again, it's not simply loss of power, it's a rapid deceleration that occurs unpredictably.  If this were to happen just as a car was cutting too close to me, it would cause an accident.  Dialing back the torque by a few percent isn't appealing, since you're giving up power everywhere to prevent something that happens only at high speed.  Is this something that firmware could address?

This happened to me again last week.  Like before, it was transient, but unexpected and unnerving.  I noticed motor temperature jumped pretty dramatically both times this happened.

You already contacted your dealer and zero about this, right?

I asked Zero about this issue and got a reply via the dealer, as Zero don't seem to like replying to customers.

Apparently it's definitely not a known issue with the 2016 FXS (and not why they bumped up the controller spec on the 2017s). If it happens on your FXS they will fix it under warranty. Does this just mean dialing back the power a bit? Who knows.
