Sensorless control mode does not work by 0.4.9 and 0.4.10, but work by 0.4.7 and 0.4.8

Hi, i am relatively new by odrive. I have such problem: I have downloaded the versions 0.4.7, 0.4.8, 0.4.9, 0.4.10 and flashed all of them one after other with st link v2 to V3.5-48V. By the versions 0.4.7 and 0.4.8 the sensorless controll mode is working very well, but by versions 0.4.9 and 0.4.10 does not. All parameters are the same by all experiments, but the motor (Multistar 9235-100) is spinning maybe with 20 rpm (1 rotation in 3 seconds), and does not react on changing the odrv0.axis1.controller.vel_ramp_target or drv0.axis1.controller.vel_setpoint. The current in this case also remain relatively low, so the motor and driver will not be hot. (but both of versions 0.4.9, 0.4.10 does work with encoders!) Any ideas? Best regards, Konstantin
