Today i connected my interfce to communicate with the Main Bike Board of my DS 2012.
It worked well and i had acces to the MBB menu
The menu is a bit different and seem to have less commands available.
On the 2011 MBB to change a parameter we obnly had to enter SET and then the MBB was offering a value range and an exemple on the command to enter to cahnge this value.
On the 2012 it seem impossible to change the value i the SET menu, the MBB only respond: INVALID COMMAND. I have tried to write SET followed by the command but it was unsuccesfull and there was a message saying it is impossible to overwrite the value.
On the 2011 we were able to change the torque or speed mode and on the 2012 there is no command for that, probably it is directly related the the sevcon other level of programming
I have played with few command to display value and i also tested the CALSINCOS command wich i discovered it is to calibrate the encoder of the motor connected to the controller.
The first time i tried that command it returned a message saying that the value are not high enough and recommanded to spin the motor!!
So i did that while i entered a second time the CALSINCOS command and the value from the motor was read and then the motor encoder was apparently successfull calibrated to the Sevcon!!.. I was a bit nervous because i was affraid to make a mistake and have overwrited the encoder value, but when i twisted the throttle the wheel was sucessfully spining!
I was really interested to set new value of the regen % on eco and sport mode but the SET command can not take new value.
I was able to get the BMS value but there is no possibility to monitor each cell bank voltage like the 2011 MBB does. It only show the low bank and the voltage unbalance.
Here is couple of screen i grabed for you:
