board’s push-buttons and potentiometers, please refer to the “Push-
Buttons”, “Potentiometers” and “Standalone Mode: Driving a BLDC
Motor” sections later in this chapter.
Set up the Motor Control board as explained in the “Installing the
Hardware” section in the “Getting Started for AC Motors” chapter.
Get the latest release of the AK-ST7FMC Control Panel system
software from SofTec Microsystems website
(http://www.softecmicro.com), uninstall the previous version and install
the new one.
In the “\Program Files\SofTec Microsystems\AK-ST7FMC\Library”
directory there are various subdirectories, each specific for a
motor/control type. Each subdirectory contains a pre-made project
specific for that motor/control type. Copy the appropriate subdirectory
(the subdirectory that corresponds to your motor and control type) into
another location. The copied subdirectory will become your working
directory.
Run the AK-ST7FMC Control Panel by selecting Start > Programs >
SofTec Microsystems > AK-ST7FMC > AK-ST7FMC Control Panel.
You will be asked what motor type you are working with. Select the “3
Phase AC Induction Motor (Sinewave)” option and click the “OK”
button. The main AK-ST7FMC Control Panel window will open.
To run an AC motor in standalone mode (Closed Loop), you must
choose an optimum sampling time and then characterize two curves, a
Ki, Kp versus stator frequency curve and a slip frequency versus stator
frequency curve. Both curves must have two points, as illustrated
below.
