FOC Flux Linkage Detection

I'm trying to run a BlueRobotics T200 using a Flipsky 75100 at very low RPM. I've been trying out different FOC modes but can't quite get it to run smoothly. I noticed during the FOC parameter setup, when I run the flux linkage detection, the motor ramps up very smoothly and at very low RPM. How can I achieve this control? Does anyone know what mode this is running?

VECT Tool freezes after uploading lisp script

I uploaded a script to a MKS 75100 that turned out to be a permanent loop over the print method. Now VESC Tool completely freezes under Windows 10 after connecting to the controller via USB. It manages to read the hardware version, which is shown in the bottom bar, but that's it. I tried VESC express, but it is unable to establish a CAN connection too.

The auto-run checkbox was checked when uploading the script, so restarting the controller leads to the same state.

 

PPM throttle detected in Vesc Tool but has no effect on motor

I'm trying to setup a PPM throttle, input displayed in Vesc Tool but the motor doesn't respond. PPM Mapping and Input Setup Wizard show correct input values but after the wizard completes successfully the throttle has no effect. I made sure to click "Write Configuration to Vesc" and to write app config but no luck. I can control the motor with keyboard if "APP to Use" is set to "No App" but not when it's set to "PPM" or "UART and PPM".. I'm sure I'm missing something really silly but after many attempts I think i need help :) 

VESC BMS problem with LTO Battery

My electric supercharger project uses a 32s LTO battery driving a VESC 100/250.    I'm using an  ENNOID BMS which communicates to the VESC across the CAN bus.   If I check Vcell Min under BMS Limit Mode, the motor will not start.  I have Vcell min set to 2.2V and all the cells are well above that.     Is there a way to get this working?

Thanks

Steve
