L6230 output problem

Greetings,

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,

Hi,

can you share some screenshots of the PWM signals and the schematic of your board?
