10 TMCM-6212 Functional Description
The TMCM-6212 is a highly integrated controller/driver module for 6 stepper motor axes which can be controlled
via several serial interfaces (CAN, RS485 and USB – depending on firmware). Communication traffic is kept low
since all time critical operations (e.g. ramp calculations) are performed on board. The nominal supply voltage of
the unit is 12V or 24V DC. The module is designed for both, standalone operation and direct mode. Full remote
control of device with feedback is possible. The firmware of the module can be updated via one of the serial
interfaces (depending on module and firmware type).
In Figure 10.1 the main parts of the TMCM-6212 are shown:
- Microcontroller, responsible for overall control - executes the firmware (either TMCL or CANopen incl. the
communication stack)
- 6 motion controller and driver with calculation of ramps (linear and sixPoint™) and speed profiles
internally in hardware
- interface for an external (e.g. optical) incremental A/B/N encoder (differential RS422 signals) for each axis
- interface for HOME / REFL / REFR reference switches for each axis
- 4 general purpose analog / digital inputs
- 4 general purpose digital (open-drain) outputs
- Three serial communication interfaces: CAN, RS485 and USB (Micro-USB-connector). While CAN and RS485
are intended for in-system control and operation (for CANopen firmware just CAN) the USB interface may
be primarily used for parameter settings and firmware updates.
