This is the voltage selector switch to set the correct rectifier configuration to the AC input.
Prior to connection the system to the AC input, carefully check the position of SW1.
Set to 115V when applying power from 110/120VAC source, or set to 230V when
applying power from a 220/230VAC source.
Output Phases Terminal (J6)
This is the terminal for motor connection, output from 3-phase inverter circuit driven by
PWM signals to the motor (i.e. motor voltages). These signals are referenced to the
negative DC power rail, which is
NOT
a ground potential.
CAUTION: Beware of electric shock hazard. DO NOT connect any grounded test
equipment such as an Oscilloscope to these test terminals. Always isolate your
equipment from Earth Ground.
Connect the motor phase inputs (U, V, and W) from this terminal as depicted in Figure 2.
Hall Sensor connector (JP1)
This is Motor’s Hall Sensors feedback connector that allows for detecting the rotor state
and position.
RS-232 Port (J5)
A standard 9-pin D-shell female type connector (DB9F) that provides an Opto-isolated RS-
232 serial link with the PC to control and monitor the development board.
RS-232 Serial Link:
A standard 9-pin D Female connector is used for the RS-232 serial link. The pins used on
this connector are the RxD, TxD, GND, RTS, and DTR. The RTS and DTR signals provide
sufficient current to drive the Opto-couplers. The current drawn from these pins is far
below permissible limits for the RS-232 drivers.
The GUI should work with any of the available COM ports on the PC. There is no
restriction on COM port. COM1 is the GUI’s default port. The serial cable may be
connected or disconnected at any time without having to restart your computer.
MPLAB ICD2 Connector (J4)
A 6-wire RJ-11 jack is provided as a programming or In-Circuit Debugger interface. This
will also allow users to use development tools, such as MPLAB ICD2, while the board is
under power.
Note that this connector is referenced to the –DC Bus.
