    Grin Cycle Analyst settings help

    Sorry to hear it didn't work out. Id hate to think its a simple setting away from working. That being said if you are burned out by this experience and wont be confident in Grin's tech support in the future I totally get it. You bought some nice stuff there and I'm sure it wasn't cheap. Along...

    Automatic switch anti-spark for JBD BMS -- very cheap, DIY, OpenSource

    Nice work here! I was wondering about the on off function of this and most other BMS. When you command the BMS on/off does this completely eliminate the need for an anti-spark resistor or connector? I'm assuming because the BMS is solid state its not a concern. I'm going to look over your EV...

    Hard set by the laws of physics. Motors have a relatively fixed relationship between rpm and voltage. If the motor is 7.4rpm/v and you have a 48v battery then at full throttle with the wheel in the air that would be: 7.4 X 48v = 355rpm 355rpm with a 26" wheel is about 45kph. If your battery...

    49.5kph might just be the max speed for your 7.5kv motor with a 48v battery

    Yeah, what is weirding me out is that your max speed of 49.5kph is precisely half of the 99kph that the controller is set at. That is to much of a coincidence to be a malfunction. Really seems to me like a setting is causing this. Grin all axle motor is 23 poles which is what you are set for...

    Does the controller have an Erpm setting? That would be like a speed limiter.

    Ok. So just to review you currently have: -Bike operates normally on throttle up to 49.5kph -pedal assist does nothing

    If the wheel is off the ground then it will still Spin up to full speed even with very low power.

    Maybe try turning all the PAS settings off in the CA I have seen bikes set where there is a different speed limit when pedaling vs not pedaling. If that isnt it then I would think the 49.5 limit is in the controller. You could look through the controller settings to see if there are any...

    I suppose its possible it is set such that it wont operate throttle only without some pedaling being detected but I doubt it.

    Grin Cycle Analyst settings help

    That all depends. The fact that your throttle behavior is so weird leads me to believe something is causing the CA to cut your power out. So I was starting the process there. Once you are confident the bike works normally at the speed and power level you expect then the job of configuring the...

    That looks to me like the controller is considering a throttle input voltage (V out from the CA) of 1.2 to be closed throttle and 3.5v to be 100% throttle. I would set the CA throttle output to minimum 1.1v maximum 3.4v

    On my CA main screen there is a little brake lever logo that moves when the brake lever is pulled to indicate that the CA is sending and receiving brake signal.

    Grin Cycle Analyst settings help

    Does the speed shown on the CA seem reasonable with how fast the wheel is rotating? And I would turn off proportional regen while you try to figure this out. If possible see if you can find a way to turn the ebrake setting off completely. It will just be one less thing messing with the behavior...

    Grin Cycle Analyst settings help

    S should be speed. If there is a speed limit set in the CA that would indicate that the CA limiting output to stay under that setting. What does your CA say for speed when you are riding? There is a page in the CA setup where you set your wheel dia or circumference. This is what gives the CA...

    Grin Cycle Analyst settings help

    Yes I am talking about voltage. The controller is most likely looking for approximately 1v-4v of throttle. The diagnosis screen on the CA should tell you the following things. In- is the voltage the throttle handle is sending to the CA Out- throttle voltage the CA is sending out to the...

    Idk about grinEU but I am very surprised by all of this. I would normally recommend Grin to people for their first ebike build specifically because of the support. I really hope they have not gone downhill with customer service.

    Can you turn the backpedal regen off in the CA settings to make sure its not triggering? May want to turn off the regular regen as well just to rule that out. Can you watch the throttle in/out screen when it cuts out. Id like to know if the CA is cutting the out signal to the controller or if...

    I just remembered that the all axle motor has the torque sensor built into the motor so I'm better able to picture your setup. So it sounds like it might have been close to working right originally and the problem was the torque sensor not being hooked up. Loading new firmware likely cleared...

    Its a bit tough to diagnose from a distance. All my ca3 experience has been with the old version where you could measure all the individual connector pins. The modern version is nicer but harder to see what each wire is doing. Same with the older controllers. With the new phaserunner stuff i...

    Did you get anywhere on this? I have no experience messing with the PAS settings so you will have to get help with that elsewhere. But if I were you I would reduce the throttle up V per second to something way lower. Maybe try 0.5v per second. Its possible the ramp up is too fast and you are...

    Can you email someone over at ebikes.ca? In my experience they have always been thorough and quick with tech support responses. You can upload a full config file with all the settings to a CA3. Seems like they could send you one to get you close. Especially if you bought all the stuff as a kit...

    Been around since 2016 I believe. This thread is the history of the company and the development of the controllers. https://endless-sphere.com/sphere/threads/nucular-electronics-complete-kit-for-ev.75494/ When these came out there were not a lot of options for advanced highly configurable...
