Description
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 RMS (low current range, programmable) or 2A RMS (high current range, programmable, new additional range since hardware version 1.3) and 24V DC supply voltage. With its high energy efficiency from TRINAMIC’s coolStep™ technology cost for power consumption is kept down. The TMCL™ firmware supports remote control (direct mode) and standalone operation (with TMCL program being executed on the TMCM-1141 itself).
