3 Overview
As with most TRINAMIC modules the software running on the microprocessor of the TMCM-1180 consists of
two parts, a boot loader and the firmware itself. Whereas the boot loader is installed during production and
testing at TRINAMIC and remains normally untouched throughout the whole lifetime, the firmware can be
updated by the user. New versions can be downloaded free of charge from the TRINAMIC website
(http://www.trinamic.com).
The firmware shipped with this module is related to the standard TMCL™ firmware shipped with most of
TRINAMIC modules with regard to protocol and commands. Corresponding, this module is based on the
TMC428-I stepper motor controller and the TMC262A-PC power driver and supports the standard TMCL™ with a
special range of values.
The TMC262A-PC is a new energy efficient high current high precision microstepping driver IC for bipolar
stepper motors and offers TRINAMICs patented coolStep™ feature with its special commands. Please mind
this technical innovation.
All commands and parameters available with this unit are explained on the following pages.
