§
The following table summarizes how the potentiometers can be used in
Open Loop mode or Closed Loop mode for a BLDC motor.
Note: in Current mode, the W12 jumper must always select the “VARIABLE”
position to allow dynamic current control by the ST7FMC microcontroller. In
Current mode, the “POT1” potentiometer is inactive.
5.2.8 Standalone Mode: Driving an AC Motor
The following table summarizes how the potentiometers can be used in
Open Loop mode or Closed Loop mode for an AC motor.

POT1
mode, the maximum current is set in the AK-ST7FMC Control Panel
before generating the .h files.
If the W12 jumper select the “FIXED” position, the current reference
comes from the “POT1” potentiometer. The “FIXED” position can be
selected only in Voltage mode.
