6.4 Connection Diagram
WARNING
SW1 is an AC Input Voltage Selector switch. DO NOT apply 230VAC when this switch
is set to 115VAC – this will result in sever damage to the system and personal injury
due to very high voltage produced by the voltage doubler circuit on the DC bus.
Figure 2 illustrates a typical connection block diagram. The printed wiring board has been
designed to minimize ground loop currents with particular attention to reducing EMI
generation.

6.5 GUI and Micro Controller
The use of the GUI enables the user to control motor speed and direction, monitors the DC
Bus current and Fault conditions, and program motor parameters and other control factors.
The GUI also enables the users to set motor and system parameters such as motor type,
motor voltage and current, AC input voltage, and PWM frequency. In addition, it allows the
