The TMCM-1140 is an intelligent stepper motor controller/
driver module featuring the new outstanding coolStep™
technology for sensorless load dependent current control. This
allows energy efficient motor operation. With the advanced
stallGuard2™ feature the load of the motor can be detected
with high resolution. The module is designed to be mounted
directly on a 42mm flange stepper motor. It converts the motor
into a compact mechatronic device with serial bus oriented or
standalone control. The TMCM-1140 is equipped with TRINAMICs
sensOstep™ encoder with 1024 pps.
The PC based software development environment TMCL-IDE for
the Trinamic Motion Control Language TMCL™ can be down-
loaded free of charge from the TRINAMIC website. Predefined
high level TMCL commands guarantee a rapid development of
motion control applications. Communication traffic is kept very
low since all time critical operations, e.g. ramp calculation are
performed onboard.
