Tue 15th Jan 2019 - Speed up the development of your application with the Trinamic TMCM 1240 single axis stepper drive/controller from Micromech

Trinamic - TMCM 1240


The module incorporates Trinamic´s latest stepper motor drive technologies including the popular silent control mode StealthChop in its second generation and the sensorless load-dependent current scaling CoolStep. The magnetic SensOstep encoder provides safe step-loss detection even in stand still.

TMCM-1240 is a single axis motor driver/ controller module for 2-phase bipolar stepper motors. It supports SixPoint™ ramps in addition to linear ramps. It is capable of driving up to 2A RMS motor current and is designed for an operating voltage of 10...30V DC supply voltage. The device provides a Step/Dir interface, an integrated SensOstep™ encoder and support for external encoder.
