Stepper Motor Controller [&] Driver 3A/24V with CAN, stealthChop™ (no noise)

The TMCM-1276 is a complete stepper driver and controller solution with state of the art feature set. It is highly integrated and offers convenient handling via CAN interface. The TMCM-1276 includes driver electronics and a fully featured hardware motion controller. It can be used in many decentralized applications and has been designed for up to 3A RMS (4.2A peak) phase current and 24V DC nominal supply voltage.

With StealthChop™, the TMCM-1276 offers absolutely silent and smooth motor operation for lower and medium velocities. SpreadCycle™ is a high performance current controlled chopper mode for highest velocities with perfect zero crossing performance. With StallGuard2™, a sensorless load detection feature is available for automatic end step detection and load monitoring. StallGuard2™ is also used for the automatic current scaling feature CoolStep™. The TMCM-1276 comes with a CAN bus interface and four (4) digital inputs.
