TMCM-1111 stepRocker Servo

Closed Loop Stepper Motor Controller [&] Driver with up to 2.8A/30V with USB/RS485/S[&]D

The TMCM-1111 stepRocker Servo is a single axis motor controller/driver board for 2-phase bipolar stepper motors. It supports S-shaped ramps in addition to linear ramps and closed-loop operation together with an external encoder.

The driver part offers highest smoothness and precision due to a high microstep resolution and the patented spreadCycle™ chopper scheme for optimized current-zero crossing and -sine wave form. The integrated sensorless load detection stallGuard2™ and the load dependent current control coolStep™ make this board unique. This features make it the first time possible to drive a stepper motor energy efficient!

The integrated ramp- and pulse generating positioning motion controller can be attached via USB or RS485. Up to 3 driver can be controlled simultaneously. A 3-axis application can easily be build by connecting two external drivers (e.g. additional stepRocker Servo) via step [&] direction signals.

It is possible to use the stepRocker Servo with the Trinamic Motion Control Language TMCL™. The board comes with the preinstalled firmware. The integrated development environment TMCL-IDE for PC can be downloaded and used free of charge. It is possible to remote control the stepRocker Servo or to write and download complete command sequences for stand-alone use.

For the first steps only a power supply, a stepper motor and a PC are necessary.
