Host/Communication Connections

A mini-USB-to-USB certified cable and a standard DB9 male-to-female cable should

be used to connect the dsPICDEM™ MCHV Development System to the host

computer.

The communication port connectors are listed in Table 2-2. Refer to Figure 2-5 for their

exact location.

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, a motor and

a 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.

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 terminal +5V 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, connect the ter-

minals phase A, phase B, and Index to the connection nodes HA, HB, and

HC (7, 8, and 9 in Figure 2-5), respectively.
