Together with Trinamic’s integrated BLDC motor gate driver TMC603A (or with the integrated stepper motor driver TMC262), one can realize a power stage with a couple of components as demonstrated with the TMCM-AC-840 Daughter Board Kit for direct plug to the ACTEL SmartFusion™ Evaluation Kit boards or Development Kit boards.
TMCM-AC-840 Motor Control Daughter Board Kit Manual 4 Programming The voltage supplies (+VM262 and +VM603) of the TMCM-AC-840 daughter board must be Actel SmartFusion™ DISCONNECTED or SWITCHED OFF during programming of the A2F200/A2F500 device. For further help on how to program the Actel SmartFusion™ devices refer to the user guides available on the Actel website http://www.actel.com.
TMCM-AC-840 Motor Control Daughter Board Kit Manual 6 Included Motors The TMCM-AC-840 Daughter Board Kit includes two motors, which fit the daughter board and demo design – one stepper motor and one BLDC motor. The picture shows how the motors will look like.
Hall1, Hall2, Hall3 for the hall sensor interface. See the on-board printing for which pin is which signal. The kit also includes 4 self-adhesive rubber feets. If using the Trinamic motor control board with an Actel/Microsemi SmartFusion Evaluation Kit, use these feets as standoffs for the motor control board.
TMCM-AC-840 Motor Control Daughter Board Kit Manual ! Make sure there is no air gap remaining between the Actel board and Trinamic’s daughter board as it is shown in the picture below. 7.3 Connecting Motors to the TMCM-AC-840 Switch off all power supplies when connecting or disconnecting any motor to/from the TMCM-AC-840 daughter board.
, but it is 40V always as the MOSFETs are only specified for up to 40V! Trinamic recommends using two independent supplies as seen in the picture below. Nevertheless, when using only one power supply, the Jumpers JVM 1-4 must be connected via bridges. These 4 jumpers are NOT assembled on the board and the bridges to connect them are NOT included in the board kit.
TMCM-AC-840 Motor Control Daughter Board Kit Manual ! Trinamic recommends connecting all 4 jumpers (Jumper 1-4) as high currents may occur at these pins! ! When using only one power supply, the absolute maximum voltage is 40V. Otherwise the TMC262 driver IC and its MOSFET stages may get damaged.
TMCM-AC-840 Motor Control Daughter Board Kit Manual 8 Pinout Lists All Pins of the Mixed Signal Header are connected to the TMCM-AC-840 daughter board and are either used for motor control, analog and/or digital signal measurement, or are free to be used for other purpose.
21:1 with two resistors 20K Ohms and 1K Ohms. 8.5 Additional SPI Header & Jumper (only revision v1.3 and higher) The TMCM-AC-840 board has an additional header (“J9 – SPI Select”) for choosing an alternative SPI source for configuration and control of the TMC262 stepper drive IC.
TMCM-AC-840 Motor Control Daughter Board Kit Manual 8.6 Board LEDs The TMCM-AC-840 has several LEDs indicating different operating conditions of the daughter board. LED SG: This LED is placed next to the stallGuard™ logo. It is on when the TMC262 stallGuard functionality detects and signals a motor stall.
Always when (dis)connecting boards and/or components to/from the SmartFusion board and TMCM-AC-840 daughter board, switch off all power supplies. Wait until the motors are at rest. The ENABLE signal of the TMC603A BLDC motor driver must be configured as a Tristate-I/O within the FPGA as it is a shared signal with ENABLE and /ERR_OUT of the TMC603A IC.
