The TMCM-1110 stepRocker™ is a 1-axis, 2.8A/24V controller/driver with coolStep™ and encoder interface, as well as S/D in and out.

The TMCM-1110 is a universal, ultra low cost, stepper motor controller/driver module. The driver unit offers highest smoothness and precision due to a high microstep resolution. The new patented spreadCycle™ chopper scheme produces an optimised current zero crossing and sine wave form. Furthermore the integrated sensorless load detection stallGuard2™ plus the load dependent current control coolStep™ make this board unique. These great features make it for the first time possible to ‘energy efficiently’ drive a stepper motor!

Features

• 3-axis motion controller
• Driver only function
• Up to 256 times microstepping / 51200 steps./rev. with a 1,8° motor
• Memory for 2048 TMCL™ commands
• Automatic ramp generation
• ‘On the fly’ alteration of motion parameters (e.g. position, velocity, acceleration)
• StallGuard2™ sensorless high resolution motor load detection
• CoolStep™ load dependent current control
• SpreadCycle™ chopper for improved smoothness and high speed operation
• MicroPlyer™ internal microstep multiplier (16 to 256 µSteps) for lower frequency on step input
• 6x control LED

The integrated ramp- and pulse generating positioning motion controller can be attached via USB or RS485 and up to 3 drivers can be controlled simultaneously. Any 3-axis application can easily be built by connecting two external drivers (e.g. additional stepRocker™) via step & direction signals.

The smart software makes different approaches possible:

The stepRocker™ can be used with the Trinamic Motion Control Language TMCL™ and as the board comes with installed firmware and the integrated development environment, the TMCL-IDE for PC can be downloaded (free of charge). It is also possible to remotely control the stepRocker™ or to write, then download complete command sequences for stand-alone use.

As an alternative it is possible to write the firmware for the SAMSUNG microcontroller using the downloadable software tools and motion control libraries. For the initial steps only a power supply, a stepper motor and a PC are necessary.
