L6480 UVLO-Bit problem. Can't get it flip to 1.

Hello,I use the EVAL6480 Board and the STM32 F446RE as MCU to communicate to the driver.My Steppermotor [1] (not exactly this but very similar) has oer phase a resistance of 1,2 ohm.My Problem is that the motor does not turn because the UVLO flag is ...

UVLO flag always on

Hi, Using IHM03A1, I'm driving a 48V-9A motor.According to @Cristiana SCARAMEL (Employee)​ recommandations, I add 15mOhm/3W resistances in parallel of R1 and R2, so R1 and R2 value is now 13mOhm, I choosed current mode, set run current to 10.2A (132....

STPMIC1 I2C program

I have a STPMIC1E on my board, it is used with a STM32MP157 chip. I am currently trying to program the PMIC IC via the GUI but it won't connect to the bus. It says USB to I2C bus not connected. Any ideas?Thanks

Resolved! STEVAL-PTOOL2V1, STSPIN32F0252, Motor stall setting

The motor will stall at lower RPM,We found that the MCU did not detect a high current pull before the rotor stalled.Stop the motor because of MC_LF_TIMER_FAILURE (RUN_STAY_WHILE_STALL_MS set to 2000, should be enough),Is there any parameter that can ...
