5 The Hardware

5.1 Connectors

The TMC603 evaluation board is equipped with the following connectors:

Connector

Name

Function

Power supply

X201

This is the connector for power supply. The voltage must be between 12V

and 48V DC. The positive pole is marked “12V-48V”. The negative pole is

marked “GND”. The board is protected against reverse polarity by a diode

(from evaluation board version 1.10).

Motor coil output

X301

This is the connector for a three phase BLDC motor. Connect the coils to

the pins marked “U”, “V” and “W”.

Hall sensor

X112

This is the connector for optional hall sensors. The first two pins are for

power supply of the hall sensors. The voltage is 5V DC. The positive pole

is marked “+5V” and the negative pole is marked “GND”. The other three

pins are the inputs for hall signals. Connect the hall signals to the pins

marked “INPUT1”, “INPUT2” and “INPUT3”.

CAN

X115

This Sub-D connector is a CAN interface for communication to the PC.

Additionally you need a Trinamic USB-2-X interface converter which

allows easy interfacing the evaluation board to a PC running under

Windows 98/2000/XP via the USB Interface. Please see also the USB-2-X

manual for a description of the USB-2-X interface converter. The CAN

interface uses a baud rate of 500 kbaud. The pin assignment of this

connector is as follows:

Pin 2 CAN low

Pin 3 GND

Pin 6 GND

Pin 7 CAN high

RS232

X116

This Sub-D connector is a RS232 interface. If the evaluation board is not

used with the USB-2-X interface converter, a RS232 plug can be

connected here which also allows interfacing the evaluation board to a PC.

The RS232 interface uses a baud rate of 115200 baud, eight data bits,

one start bit, one stop bit and no parity. Only the pins 2, 3 and 5 are

connected. The assignment of this connector is as follows:

Pin 2 RxD

Pin 3 TxD

Pin 5 GND
