INFO
The TMCM-351 is a powerful triple axis 2-phase stepper motor
controller/driver module with optional encoder interface. Using
the integrated additional I/Os it even can do complete system
control applications. The motors and switches can be connected
easily with screw or crimp style connectors. The connection
of the I/Os, the encoder and SPI can be done via a two row
header. The TMCM-351 comes with the PC based software devel-
opment environment TMCL-IDE for the Trinamic Motion Control
Language (TMCL). Using predefined TMCL high level commands
like „move to position“ or „constant rotation“ rapid and fast
development of motion control applications is guaranteed.
The TMCM-351 can be controlled via RS-232, RS485, CAN or
USB interface. Communication traffic is kept very low since all
time critical operations, e.g. ramp calculation are performed on
board. A user TMCL program can be stored in the on board EE-
PROM for stand-alone operation. An optional firmware allows to
control the TMCM-351 via CANopen. The firmware of the module
can be updated via the serial interface. With the stallGuard™
feature it is possible to detect overload and stall of the motor.
