I'm designing project for Speed Control of 3-Phase Induction Motor with STGIPS30C60-H. I'm driving with microcontroler trough optocoupler. The motor is rotating in with desired speed about one minute and after stop. After that STGIPS30C60-H does not operate any more. I measure voltage on SD/OD is about 1V. Also one optocoupler is break connected to HINw.

Please, send me information what to do.

Best regards,

Mitko Tolev

Dear @BAbde.1​ 

There is now in the last SDK version demonstration firmware example projects for ACIM showing how the STM32 MC SDK can be used to drive an asynchronous induction motor (ACIM) in field-oriented control (FOC) using a sensorless state observer algorithm to estimate the electrical and mechanical speed and position of the rotor and the rotor flux, or in V/F open-loop sensorless mode.

Please have a look on our STM32 Motor Control Knowledge database here: https://wiki.st.com/stm32mcu/wiki/STM32MotorControl:SDK_AC_induction_motor .

Best regards
