Mechanical and electrical interfacing

Controller/driver board size and mounting holes

The dimensions of the controller/driver board (TMCM-164) are approx. 42mm x 42mm in order to fit on the back side of a 42mm NEMA 17 brushless DC motor. Maximum component height (height above PCB level) without mating connectors is around 10mm and about 3mm below PCB level. There are two mounting holes for M3 screws for mounting the board directly to a NEMA 17/42mm flange size brushless DC motor.
Figure 4.1: Module dimension and position of mounting holes

Connectors

The controller/driver board offers 6 connectors including the motor connector which is used for attaching the motor coils to the electronics. In addition to the power connector there is one connector for (optional) motor hall sensor signals and one connector for (optional) incremental encoder signals. For serial communication a mini-USB connector has been integrated on-board. There is an additional connector for RS485 serial communication, 3 general purpose inputs and one output. General purpose inputs and output may have dedicated functionality depending on firmware.

Table 4.1: Connector for power supply

• Please note, that there is no protection against reverse polarity and only limited protection against voltages above the upper maximum limit. The power supply typically should be within a range of +9 to +28.5V.
• When using supply voltages near the upper limit, a regulated power supply is mandatory. Please ensure that enough power filtering capacitors are available in the system (2200µF or more recommended) in order to absorb mechanical energy fed back by the motor in stalling conditions and in order to prevent any voltage surge e.g. during power-on (especially with longer power supply cables as there are only ceramic filter capacitors on-board). In larger systems a zener diode circuitry might be required in order to limit the maximum voltage when the motor is operated at high velocities.
• The power supply should be designed in a way that it supplies the nominal motor voltage at the desired maximum motor power. In no case shall the supply value exceed the upper voltage limit.
• To ensure reliable operation of the unit, the power supply has to have a sufficient output capacitor and the supply cables should have a low resistance, so that the chopper operation does not lead to an increased power supply ripple directly at the unit. Power supply ripple due to the chopper operation should be kept at a maximum of a few 100mV.

Guidelines for power supply:

• keep power supply cables as short as possible
• use large diameters for power supply cables
• add 2200µF or larger filter capacitors near the motor driver unit especially if the distance to the power supply is large (i.e. more than 2-3m)

Input/output circuits

Hall sensor input
The hall sensor input circuit supports +5V push-pull (TTL) and open-collector hall sensor signals. In order to support open-collector signals the input circuit offers 2k7 pull-up resistors to +5V (generated on-board from power supply voltage).

Figure 4.3: Hall sensor input circuit

Encoder input

The encoder input circuit supports +5V push-pull (TTL) and open-collector hall sensor signals. In order to support open-collector signals the input circuit offers 2k7 pull-up resistors to +5V (+5V generated on-board from power supply voltage).

General purpose inputs/outputs

On-Board LEDs

The board offers three LEDs in order to indicate board status. The green LED turns on in case +5V from the on-board DC/DC switching regulator is available. The function of the two red LEDs is dependent on the firmware version. With standard TMCL firmware one red LED indicates high temperature (Temperature Warning) and the other will turn on in case the motor current reaches the limit that has been previously set in software (Overcurrent).

BEHAVIOR OF LEDS WITH STANDARD TMCL FIRMWARE

approx.. 100°C and remains permanently on when temperature exceeds approx.. 120°C
Overcurrent| Red LED, on when motor current reaches MaxCurrent setting in software

Operational ratings

The operational ratings shown below should be used as design values. In no case should the maximum values been exceeded during operation.

Functional description

In Figure 7.1 the main parts of the TMCM-1640 module are shown. The module mainly consists of the Cortex™-M3 CPU, TRINAMICs TMC603A 3-phase pre-driver, the MOSFET driver-stage, and the USB 2.0 interface.

System architecture

The TMCM-1640 integrates a microcontroller with the TMCL™ (Trinamic Motion Control Language) operating system. The motion control real-time tasks are realized by the TMC603A.

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 ROM of the microcontroller holds the TMCL™ operating system. The EEPROM memory is used to permanently store configuration data. The microcontroller runs the TMCL™ operating system which makes it possible to execute TMCL™ commands that are sent to the module from the host via the interface. The microcontroller interprets the TMCL™ commands and controls the TMC603A which executes the motion commands.
The TMCL™ operating system can be updated via the host interface. Please use the latest version of the TMCL-IDE to do this.

TMC603A 3-phase 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. It integrates shunt resistor based current measurement. Protection and diagnostic features as well as a step- down switching regulator further reduce system cost and increase reliability.
