5.2.7 Standalone Mode: Driving a BLDC Motor
A BLDC motor can be driven in Current mode or Voltage mode. Depending
on the driving mode, you must set the W12 jumper accordingly. Furthermore,
in either mode, you can drive the motor in Open Loop mode or Closed Loop
mode.
The W12 jumper must be set as follows.

“ON/OFF”: starts or stops the motor.
“RESET”: resets the ST7FMC microcontroller.
“POT1”: current reference setting (for BLDC motor only).
“RV1”, “RV2”, “RV3”: open loop and closed loop settings.
If the W12 jumper selects the “VARIABLE” position, the current
reference comes from a PWM-generated, RC-filtered signal generated
by the ST7FMC microcontroller. The “VARIABLE” position may be
selected either in Current mode or Voltage mode. Note: In Voltage
