TMCM-1110 StepRocker

Stepper Motor Controller & Driver, 2.8A/24V, USB/RS485/S&D

The TMCM-1110 StepRocker™ is an universal low cost stepper motor controller/driver module.

The driver part offers highest smoothness and precision due to a high microstep resolution and the new patented SpreadCycle™ chopper scheme for optimized current-zero crossing and -sine wave form. The integrated sensor less 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™) via step [&] direction signals.

It is possible to use the StepRocker™ 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™ or to write and download complete command sequences for stand-alone use.

Alternatively for TMCM-1110 StepRocker an open source source code library TMCL LITE is available. Sourcecode can be accessed via GitHub.

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