The application is prepared for operation when connected to a power
supply.
The drive is controlled by the RUN/STOP switch (SW1). The motor
speed is set by the SPEED potentiometer (P1). If successful, the
3-phase BLDC motor will be spinning.
If the RUN/STOP switch is set to the RUN position when the application
is powered on, toggle the switch between the RUN and STOP positions
to enable motor spinning. This is a protection feature preventing the
motor from starting after power on.
In the case of a DC Bus over-current, DC Bus over-voltage or DC Bus
under-voltage, the fault protection disables the drive. The DC Bus
over-current fault state can be left by turning the RUN/STOP switch to
the stop position. DC Bus over-voltage or DC Bus under-voltage fault
state can be left by MCU reset.
