TRINAMIC Motion Control extends its portfolio of TMCM embedded motor control modules. Following to the success of the TMCM-1110-StepRocker single axis board, the TMCM-1111-StepRocker-Servo is designed to be as easy to use as its sibling, but with additional closed-loop stepper motor servo functionality.

The board drives 2-phase bipolar stepper motors from 500 mA_RMS to 1.0 A_RMS or from 1.1 A_RMS to 2.8 A_RMS selectable by jumpers. Utilizing TRINAMIC’s highest performance stepper motor driver IC for external MOSFETs TMC262 and the dedicated closed-loop motion controller TMC4361, the TMCM-1111 is a cost- and energy-efficient stepper motor servo controller for stepper motors with a/b/n quadrature encoders. Ideal for liquid handling and handling sensitive goods, the S-ramp controller allows for precise and fast positioning.

The TMCM-1111 can be controlled via RS485 or USB serial interfaces (CAN retro-fit option) and is designed as open source hardware - schematics and layout are available for download. A simplified code project for the NXP Kinetis microcontroller including TRINAMIC’s TMCL protocol can be downloaded as well. The credit card-sized board has dimensions of 85 mm x 55 mm.
