Hello,
I'm currently converting a Piaggio Ape 50 3 wheeled italian "tuktuk". I'm using in the build a 3kw "mid drive" motor, connected to original shaft via a chain, with a 5:1 reduction ratio.
The motor is driven by a Sevcon Gen4 controller. I have DVT software and Ixxaat USB to Can adapter, and I have a somewhat good understanding of the software and controller configuration.
However, my chain isn't perfectly tensioned, as the pulley isn't perfectly centered. So after any acceleration, when the vehicle comes to coasting, the motor is very jittery and transmits a strong vibration to the entire vehicle.
My guess is that there's some parameters to change in the pid control of the motor, but I have no clue where to start.
is there any Sevcon Wizard here who could help me ?
I know I could put on a chain tensioner but I'd really like to patch this issue software wise.
Thank you
