please and please I also need help with my lift. Every single help on my Otis Gen2 will be highly appreciated. my Otis lift motor suddenly start to vibrate and the whole car shaking seriously on stopping. I adjusted the motor encoder and tested it on normal run just to see if it okay. i didn't try to do the learning because it started working fine again just as usual. so we start using the lift again, so after some few runs, the lift stopped working again. the car got stocked at the ground floor. the lift was shotdown. the event log and the error codes shown on my service too is as follows: 912- No floorInfo, 528-profile err, 725-UCM BrkBlock, 400- Brake S1 SAS, 909-CAN BusOff, 902-CAN err, 000-power on
