We are using this component in a board with a STM32F103CB with FOC firmware 4.0, the parameters code are generated via most recent Motor Control Workbench.

The 6 PWM signals are well generated, and the L6230 is being powered with a 30 Volts. DC power line. VSA,VSB are correctly connected, as technical document suggested. VBOOT is well generated and VCP output shows a 10 V square signal of 616 Khz, that it is correct, according to technical doc.

But the output at OUT1,OUT2 and OUT 3 reach a maximum of 3 Volts. Due to this the motor is not moving. Where is the problem? Any tip suggestion?

Thanks in advance,
