Hello,

I am working on BLDC motor driver. I am use STM32G431 as control unit with Motor Control Workbench and DRV8323RH gate driver. I have problem with getting the motor to spin, as soon i I start it, i am getting under voltage error. And see some overcurrent problem at power stage. It happent both in 3 and 6 PWM control mode.

It seems like it is software control issue. Does anyone have expierience with Motor Contron on Texas DRV83xx drivers?

Please ensure that the PWM channels are connected correctly (TIM1_CH1 to INHA, TIM1_CH1N to INLA, TIM1_CH2 to INHB and so on). Please verify that the Power Stage>Driving Signal Polarity for high side and low side is set correctly.
