2.3.2 Host/Communication Connections
A mini-USB to USB certified cable or a standard DB9 male-to-female cable should be
used to connect the dsPICDEM™ MCHV-3 Development Board to the host computer.
The communication port connectors are listed in
Table 2-2 . Refer to Figure 2-5 for their
exact location.
TABLE 2-2: I/O CONNECTORS
2.3.3 Connection Sequence
The recommended connection sequence is listed below. The user should ensure that
the following sequence is met before connecting the system to the mains, the motor
and the host computer.
1. Connect the motor terminals, R, Y and B (also known as RWB, or 123 or ABC),
to the connection nodes, M1, M2 and M3 (4, 5 and 6 in Figure 2-5 ), respectively,
and connect the motor ground to the ground terminal provided on the board
chassis.
2. Follow the next steps if position sensors are utilized to control the motor. If not,
proceed to Step 3.
a) If the motor position is sensed with Hall sensors, connect the Terminals A, B
and C to the connection nodes, HA, HB and HC (7, 8 and 9 in Figure 2-5 ),
respectively. Also, connect the positive te5V to the connection node,
+5V, and the ground terminal to the connection node, GND (10 and 11 in
Figure 2-5 ).
b) If the motor position is sensed with a Quadrature Encoder Interface, connect
the terminals, Phase A, Phase B and index, to the connection nodes, HA, HB
and HC (7, 8 and 9 in
Figure 2-5 ), respectively.
3. Connect the communication ports.
a) If RS-232 communication is used, connect the DB9 male connector to the
RS-232 port. Connect the other end to the host PC (12 in Figure 2-5 ).
b) If USB communication is used, connect the mini-USB male terminal to the
mini-USB female connector, labeled “USB” (12 in Figure 2-5 ). Connect the
other end to the host PC.
Number Name Type
13 USB to UART Connector Input/Output
14 RS-232 to UART Connector Input/Output
15 USB Connector for the Starter Kit on the Board Programmer/Debugger Input/Output
16 Non-Isolated ICSP™ Connector for Device Programming/Debugging Input/Output
17 Matrix Board Input/Output
Note:
Before making any connection, verify that the system is not powered and it
is fully discharged. The system is completed discharged when the red
D13 LED is off.
Note:
The Microchip serial emulator driver (
mchpcdc.inf
) should be installed
on your PC in order to activate the USB-to-serial emulator. The emulator
can be obtained from the dsPICDEM™ MCHV-3 Development Board
