    TMCM-343 Hardware Manual (V1.07 / 2011-JUN-08) 2 Features The TMCM-343 is a compact and versatile triple axis 2-phase stepper motor controller and driver module. It provides a complete motion control solution at a very small size for embedded applications. Using the integrated additional I/Os it even can do complete system control applications.

    TMCM-343 Hardware Manual (V1.07 / 2011-JUN-08) 5.3 Power supply requirements Two different power supplies have to be provided for the TMCM-343: +5VDC for the controller part and +7… 34VDC for the motor supply. Please connect all listed pins for the power supply inputs and ground in parallel.

    TMCM-343 Hardware Manual (V1.07 / 2011-JUN-08) 7 Functional description In Figure 7.1 the main parts of the TMCM-343 module are shown. The module mainly consists of a processor, a TMC428 motion controller, three TMC246 stepper motor drivers, the TMCL™ program memory (EEPROM) and the host interfaces RS232, RS485 and CAN.
  • Page 13: Tmc428 Motion Controller

    The TMCM-343 module is equipped with a circuit that extends the microstep resolution of the TMC246 chips to true 64 times microstepping. The maximum peak coil current of each stepper motor driver chip is 1500mA.

  • Page 16: Stallguard™ - Sensorless Motor Stall Detection

    7.5 stallGuard™ - sensorless motor stall detection The TMCM-343 modules are equipped with the stallGuard™ feature. The stallGuard™ feature makes it possible to detect if the mechanical load on a stepper motor is too high or if the traveler has been obstructed.
  • Page 17: Stallguard™ Profiler

    As it is very seldom that exactly the same result is produced when recording a profile with the same parameters a second time, always two or more profiles should be recorded and compared against each other. Copyright © 2011, TRINAMIC Motion Control GmbH & Co. KG...
  • Page 18: Reference Switches

    10k pull-up resistors for reference switches are included on the module. 7.6.1 Left and right limit switches The TMCM-343 can be configured so that a motor has a left and a right limit switch (Figure 7.8). The motor stops when the traveler has reached one of the limit switches.

    (please see the TMCM-341/342/343 TMCL™ Firmware Manual for information on this). 7.10 Microstep resolution The TMCM-343 supports a true 64 microstep resolution. To meet your needs, the microstep resolution can be set using the TMCL™ software. The default setting is 64 microsteps, which is the highest resolution.
  • Page 21: Putting The Tmcm-343 Into Operation

    TMCM-343 Hardware Manual (V1.07 / 2011-JUN-08) 8 Putting the TMCM-343 into operation On the basis of a small example it is shown step by step how the TMCM-343 is set into operation. Experienced users could skip this chapter and proceed to chapter 9.
  • Page 22: Migrating From The Tmcm-303 To The Tmcm-343

    The connector of the TMCM-343 is identical to the connector of the TMCM-303, so that a TMCM-343 can just be plugged into the slot for a TMCM-303 (it can also use the same base boards as the TMCM-303). Also the TMCL™ firmware of the TMCM-343 is highly compatible with the TMCM-303.

    12 CANopen The TMCM-343 module can also be used with the CANopen protocol. For this purpose, a special CANopen firmware has to be installed. To do that, download the latest version of the TMCM-343 CANopen firmware from the Trinamic website or use the version provided on the TechLib CD and install it using the firmware update function of the TMCL-IDE (Setup/Install OS).
