10 Functional Description
The TMCM-1240 is a highly integrated single axis controller/driver module for stepper motors with up-to
2A RMS / 2.8A peak motor coil current. The TMCM-1240 can be controlled via RS485, CAN or USB serial
interfaces.
The TMCM-1240 comes with the PC based software development environment TMCL-IDE for the Trinamic
Motion Control Language (TMCL
™
). Using predefined TMCL
™
high level commands like move to position
a rapid and fast development of motion control applications is guaranteed. Whereas the boot loader is
installed during production and testing at TRINAMIC and remains usually untouched throughout the whole
lifetime, the firmware can be updated by the user via any serial interface.
Communication traffic is kept low since all time critical operations, e.g. ramp calculation, are perfomrmed
on-board. Full remote control of the device with feedback is possible. The firmware of the module can be
updated via any of the serial interfaces.
The TMCM-1240 module contains the following main components:
• Microcontroller (ARM Cortex-M3™), responsible for overall control and communication
•
Highly integrated advanced stepper motor controller supporting linear and unique 6-points ramps in
hardware
•
Advanced stepper motor driver with stallGuard2
™
and coolStep
™
with MOSFET driver stage (8x
power N-MOSFETs for bipolar stepper motor)
• RS485, CAN and USB transceivers
• On-board voltage regulators (+5V and +3V3) required for supply of all on-board digital circuits
