Bafang M620 setup CAN parameters.

[jlfuente]

Has anyone used this device to refresh the parameter data of a M620 Bafang motor? Any positive experiences?

K1 Flash - setup CAN motor parameters, Firmware update and Calibration & K1 BlackBox 3 & brand new K1 BatteryBox Racing

Dear Bafang ebikers Would you like to set or tune motor controller parameters? K1 Flash is compatible with all Bafang CAN bus motors (5 pin connector with "house" shape). Also can download motor firmware for M500, M510 and M600 motors and run Calibration. Simple as 1, 2 ,3 ... 1. Insert...

Does it allow to do what other devices allow for UART protocol?

Hello.

With old M620 CAN firmares, you can not set much, everything is hardcoded. Only speed limit, wheel and circumference.

But there is latest firmware 41.1 where u can set also power levels. (Throttle speed hardcoded here - unfortunatelly)

But there is latest firmware 41.2 where u can set also power levels. (Throttle speed hardcoded here - unfortunatelly)

Thanks very much for your response.

 

[Dado]

Saw it just now. Sorry.
That 41.1 is 48V.

Here is latest thanks email from a customer from Australia - they have lot of M620 motors there. Customer did tried the latest firmware 41.1 and we trying figuring out how that Eco/Sport settings works. In original Besst programmer also possible to setup only 5 levels. Dont understand why Bafang came up with this Eco/Sport mode - and only in M620. So far it looks like ECO power is lowered over some constant. And there is hardcoded speed limits for throttle. Each PAS level has different speed for throttle: 10, 15 ,20, 25, 30 kmh. Luckily pedalling speed still possible to set. But I am afraid they will hardcode pedalling speed also soon with new firmwares.

"Regarding the 3-Sports mode, it is definitely delivering more power. Maybe I did not snap the pic at the correct time. I was riding one-handed up a hill I will do some proper testing next weekend.
Also, it is not limited to 25kmph in sports mode, I will also test this further next weekend.
All in all, this bike is now 10 x better than it was. Thank you K1

Lionel"

What's the output of 41.1?
How can I get that .bin file?

Quick question guys,

Has anyone tried this firmware on a CANBus M620 motor?

I don't have a CANBus M620 to test it on but would appreciate feedback before passing this onto someone who has made an enquiry

 

[Dado]

Hello Neeko.

Have a note at this firmware it has lowered power at low PAS: 3,6,12,20,30A
Attaching version 1.2, little newer, if somebody wants to try. Is great as supports also power setting.

 

[Neeko DeVinchi]

Much appreciated @Dado

 

[mystic]

Much appreciated @Dado

How did this one turn out?

 

[Dado]

It is good, also with power adjustment support. Over K1 Flash, Besst Pro, Go+ or DPC010

Does this also grant you the ability to set parameters in the canbus display similar to how the eggrider did for the uart version?

I do not know how eggrider UART works, but all Bafang CAN displays work with this controller the same way they work with Bafang controllers (select pedal assist level, trigger walk mode, show mileage, show speed, show effort (or I do not know what those graphs on the newest Bafang displays mean when you spin the pedals), allow to select speed and distance units, show battery charge level, etc).

For setting parameters like power, voltage, battery cells, rotary encoder calibration, torque sensor calibration, sensitivity, throttle curves, PAS behavior and other tunes you need to use VESC Tool application (using your phone or PC through integrated Bluetooth, or through VESC Express dongle through USB or Wi-Fi, or Bluetooth, or connecting directly to the controller USB).

Hey, are you still creating the adapters? I'm interested.

I have an innotrace. Also full unlocked, log-in bypass privileges up to 3000w. God mode.

OK. If you want to replace your M620 by an M560/510 or M600/500 there are INNOTRACE controllers for those motors too

Today is the day guys! Now INNOTRACE belongs to the people! It is like a Christmas miracle! The PCB and the firmware have been updated. I recommend to revive the old thread and include this into the first post, but it is up to you how you want to manage it...
