Trinamic TMCM-1111 extends its portfolio with a cost efficient stepper motor servo controller module

The TMCM-1111-StepRocker-Servo extends the successful StepRocker™ family by a closed-loop stepper motor servo controller.

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 TMCM-1111-StepRocker Servo is a single axis stepper motor controller/driver module for closed loop stepper motor servos. The device is powered by Trinamic stallGuard2™, coolStep™ and spreadCycle™ chopper technology and has a S-shaped ramp generator.

The TMCM-1111 is capable of driving up to 2.8A of current from each output. It is designed for an operating voltage of 10...30V. The device provides a RS485, USB, S/D and encoder interface. An integrated protocol processor supplies a high level TMCL communication.

The new board drives 2-phase bipolar stepper motors from 500mA to 1.0A RMS or from 1.1A to 2.8A 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 credit card-sized board has dimensions of 85mm x 55mm.
