1 Features
The TMCM-1141 is a single axis controller/driver module for 2-phase bipolar stepper motors with state of
the art feature set. It is highly integrated, offers a convenient handling and can be used in many
decentralized applications. The module can be mounted on the back of NEMA 17 (42mm flange size)
stepper motors and has been designed for coil currents up to 1.1 A RMS and 24 V DC supply voltage. With
its high energy efficiency from TRINAMIC’s coolStep™ technology cost for power consumption is kept down.
The TMCL™ firmware allows for both, standalone operation and direct mode.
