Part details & applications

The TMCM-140-42-SE is an intelligent stepper motor controller and driver module to be mounted directly on a 42mm flange stepper motor. This module converts the motor into a compact mechatronic device with bus oriented or stand-alone control. The motor, switches, power and the multi-purpose I/Os can be connected with small pluggable connectors. The ChopSync™ feature allows high speed movement without resonance problems. The TMCM-140-42-SE comes with the PC based software development environment TMCL-IDE for the ADI Trinamic Motion Control Language (TMCL™).

Using predefined TMCL™ high level commands like "move to position" or "constant rotation" a rapid and fast development of motion control applications is guaranteed. The TMCM-140-42-SE can be controlled via RS232, RS485, CAN or USB interface. Communication traffic is kept very low since all-time critical operations, e.g., ramp calculation are performed onboard. The TMCL™ program can be stored in the on board EEPROM for stand-alone operation. The firmware of the module can be updated via the serial interface. With the StallGuard™ feature it is possible to detect motor overload or motor stall. An optional firmware allows to control the module with the CANopen^TM protocol.
