Motor startup in sensored mode

Hi everyone

[PN]: STM32F303RE, X-Nucleo IHM17M1, Faulhaber 0620-006B
[VERSION]: 6.4.1
[TOOL]: MC Workbench setup
[DETAILS]: Hi everyone. I'm currently trying to configure the aforementioned hardware for motor control. My question is in regard with sensored startup. In sensorless mode, the open loop motor startup is configured in the "sensorless startup parameters" window in "Speed sensing config" settings. However, when in sensored mode (hall effect), there is no option to do configure the startup behaviour of the motor. I have tried both 6Step and FOC, and in both modes the motor fails to startup, but operates normally once I give it a "nudge". At least for my application, it seems like an open-loop startup is still required. Is there any way to accommodate this, or do I have a misunderstanding of the implementation in some regard.
