Why does VBUS voltage always show 0V (Under Voltage Fault) in Monitor section of ST Motor Control workbench?

[Ritul Shah]

I have developed a custom board using STSPIN32F0A for bldc motor control application. When I am trying to test with Bull Running BR2804 motor, after configuration of pins when I check in Monitor Section, VBUS voltage is 0 Volt and a continuous Undervoltage fault is detected.

What can be the problem?

Any quick help would be appreciated.
