Getting Started

You need

TMC2225-EVAL
Landungsbruecke or Startrampe with latest firmware
Eselsbruecke
Stepper motor (e.g. QMot line)
USB interface
Power Supply
Latest TMCL-IDE V3.0 and PC
Cables for interface, motors and power

Precautions

Do not mix up connections or short-circuit pins.
Avoid bundling I/O wires with motor wires.
Do not exceed the maximum rated supply supply voltage!
Do not connect or disconnect the motor while powered!
START WITH POWER SUPPLY OFF!

Instruction

First Start-Up

Make sure that the latest version of the TMCL-IDE 3.0 is installed. The TMCL-IDE can be downloaded from www.trinamic.com/support/software/tmcl-ide/.
Open the TMCL-IDE and connect the Landungsbruecke or Startrampe via USB to the computer. For Windows 8 and higher is no driver needed, on Windows 7 machines the TMCL-IDE is installing the driver automatically.
Verify that the Landungsbruecke or Startrampe is using the latest firmware version. The firmware version is shown in the connected device tree.
The TMCL-IDE 3.0 needs room to show all important information and to provide a good overview. Therefore, arrange the main window related to your needs. We recommend using full screen. For evaluation boards it is essential to have access to the registers. Therefore open up the Register Browser (left side). For a better view click top right on the normal icon to get a maximized register browser window.
The TMCL-IDE includes a dialogue for diagnostic tasks. Further, the dialogue provides an overviewof the connected motion controller and driver chips. Thus, a window pops up immediately after connecting the evaluation kit the first time. The window shows the actual status of the connections. The second tab of the dialogue offers the possibility to choose basic settings or to reset the module to factory defaults.

Hardware Information

All design files for our evaluation boards are available for free. We offer the original ECAD files, Gerber data, the BOM, and PDF copies. Typically, the ECAD files are in KiCAD format. Some (older) evaluation boards may only be available in Eagle, Altium, or PADS format. Please check schematics for Jumper settings and input/output connector description. The files can be downloaded from the evaluation boards’ website directly at out homepage: TRINAMIC Eval Kit homepage.

Note If files are missing on the website or something is wrong please send us a note.

Evaluation Features in the TMCL-IDE

This chapter gives some hints and tips on using the functionality of the TMCL IDE, e.g., how to use the velocity mode or some feature-based tools.

Note In order to achieve good settings please refer to descriptions and flowcharts in the TMC2225-SA data sheet. The register browser of the TMCL-IDE provides helpful information about any currently selected parameter. Beyond that, the data sheet explains concepts and ideas which are essential for understanding how the registers are linked together and which setting will fit for which kind of application. For getting more familiar with the evaluation kit in the beginning of your examinations, drive the motor using velocity mode and/or positioning mode first. Beyond this, the direct mode function can be used. This way, TMCL commands can be sent to the evaluation board system.

Velocity Mode
To move the motor in velocity mode, open the velocity mode tool by clicking the appropriate entry in the tool tree. In the velocity mode tool you can enter the desired velocity and acceleration and then move the motor using the arrow buttons. The motor can be stopped at any time by clicking the stop button. Open the velocity graph tool to get a graphical view of the actual velocity.

Note In order to get a more accurate graphical velocity view, close the register browserwindow when using the velocity graph.

Configuration

Position Mode
To move the motor in position mode, open the position mode tool by clicking the appropriate entry in the tool tree. In the position mode tool you can enter a target position and then start positioning by clicking the Absolute or Relative Move button. The speed and acceleration used for positioning can also be adjusted here. Open the position graph tool to get a graphical view of the actual position.

Note In order to get a more accurate graphical position view, close the register browser window when using the position graph.

Configuration

ChipClick
To configure the control pins for the TMC2225-EVAL, open the ChipClick tool by clicking the appropriate entry in the tool tree. To view a description of a pins possible configurations, hover the mouse over the pin in the graphical view. To change the pins state, click on it.
