Servo Controller/Driver Module Cuts Power Loss by 75 Percent


TRINAMIC Motion Control has introduced the smallest and lowest-power single-axis servo controller/driver module with integrated motion control.

The new TMCM-1321 servo controller/driver module enables two-phase bipolar stepper motors in robotics and automation equipment to optimize speed and synchronization of axes for quicker throughput while also reducing power loss by 75 percent. It features an on-board magnetic encoder and digital inputs for an optical encoder to simplify servo control for advanced feedback and diagnostics and is more than three times smaller when compared with similar stepper motor solutions.


The TMCM-1321 module features linear ramping, Trinamic SixPoint™ ramping, as well as advanced S-shaped ramping to speed effective transfer time. Trinamic’s closed-loop technology utilizes direct feedback to automatically reduce power loss by 75 percent. Together with an RS-485 interface and Trinamic’s integrated development environment, the TMCM-1321 module simplifies design and reduces stepper motor size by more than three times.
