6.2 Establishing the connection
You can establish a connection to the PC via RS23 interface and via CAN interface. In the following
these options shall be described.

6.2.1
Connection via RS232 interface
If you use the RS232 interface you need no additional hardware. Before starting the software, the
evaluation board should be connected to an RS232 interface of your PC using a null modem cable.
Then, make sure that the evaluation board is supplied with power. Thereafter, start the PC

Connection via CAN interface
If you use the CAN interface you need the TRINAMIC USB-2-X interface converter to function
correctly. Before running the program, install the TRINAMIC USB-2-X interface converter (pls. Refer
USB-2-X manual) and attach the TMC603 evaluation board to it. Then, make sure that the
evaluation board is supplied with power.
Thereafter, start the PC software by double
clicking the file “EVAL603HallFX.EXE”. Then,
select the CAN interface and the associated
CAN device that is to be used. If you press the
“Open” button the connection will established.

6.3 Selecting the operating mode
If the connection is established you can select
the operating mode by pressing the pull-down
menu. The several modes are “Block, HallFX,
Open Loop”, “Block, HallFX, Closed Loop”,
“Block, Hall Sensor” and “Sine, HallFX, Closed
Loop”. You can only change the operating
mode if the motor is stopped. If you select the
“Block, Hall Sensor” mode you can additionally
select the chopper mode. Three chopper
modes are available (Dual chopper, Low side
chopper, High side chopper). Please press the
“Set” button to send these data to the
evaluation board.

6.3.1
The operating mode “Block, HallFX, Open Loop”
The first mode is the sensorless block commutation with hallFX™ and open loop current control. In this
mode the motor will start with block commutation by using an open loop ramp up. This means that the
PWM duty cycle is increased in a definite time. Thereafter, the motor will run by using the BLDC back
EMF commutation hallFX™.

The operating mode “Block, HallFX, Closed Loop”
The second mode is the sensorless block commutation with hallFX™ and closed loop current control.
In this mode the motor will start with block commutation by using a closed loop ramp up. This means
that the closed loop control limits the current. The PWM duty cycle is increased depending on the
measured current. Thereaf

The operating mode “Block, Hall Sensor”
The third mode is the block commutation with hall sensors. In this mode the motor runs with hall
sensors so that no ramp up procedure is necessary. You can additionally select the chopper mode.
Three chopper modes are available: Low side chopper, high side chopper and dual chopper (default).
