8 Functional description

In figure 8.1 the main parts of the TMCM-1630 module are shown. The module mainly consists of the

Cortex™-M3 CPU, TRINAMICs highly integrated TMC603 BLDC motor pre-driver, the MOSFET driver stage,

different interfaces (depends up-on which option you have chosen), the inputs, and the outputs (open

drain).

8.1 System architecture

The TMCM-1630 integrates a microcontroller with the TMCL™ Firmware or CANopen. The motion control real-

time tasks are realized by the TMC603A.

8.1.1 Microcontroller

On this module, the ARM Cortex-M3™ CPU 32-bit processor is used to run the TMCL™ operating system and

to control the TMC603A. The flash memory of the microcontroller holds the TMCL™ operating system. The

EEPROM memory is used to permanently store configuration data. The microcontroller runs the TMCL™ or

CANopen operating system which makes it possible to execute commands that are sent to the module from

the host via the interface. The microcontroller interprets the commands and controls the TMC603A.

The TMCL™ operating system can be updated via the host interface. Please use the latest version of the

TMCL-IDE to do this.

8.1.2 TMC603A pre-driver

The TMC603A is a three phase motor driver for highly compact and energy efficient drive solutions. It

contains all power and analog circuitry required for a high performance BLDC motor system. The TMC603A is

designed to provide the frontend for a microcontroller doing motor commutation and control algorithms.

Integrated hallFX™ (pat.) allows for sensorless commutation. Protection and diagnostic features as well as a

step down switching regulator reduce system cost and increase reliability.
