BEMF plot not working with VESC6

Hello, 

my BEMF plot does not work with multiple VESC6s and VESC tool versions. Has anyone seen this before? Do you know how to fix it? This plot was taken with VESC tool 1.06. The current and other plots look correct.

The BEMF cannot be measured while the motor is driven in FOC mode, as the MOSFETs always are connected to one of the rails. To get the BEMF shape, you have to spin up the motor, stop driving it and then activate the sampling before it has slowed down. You can also turn it manually and then activate the sampling.
