Product Usage Instructions

Getting Started

Before using the TMC2300-EVAL, ensure that you have the following:

The latest version of TMCL-IDE 3.0 installed, which can be downloaded from www.trinamic.com/support/software/tmcl-ide/
A computer with USB ports to connect the Landungsbruecke

You need

TMC2300-EVAL
Landungsbruecke with latest firmware. (The Startrampe does not support the UART interface.)
Eselsbruecke bridge board
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 voltage!
Do not connect or disconnect the motor while powered!
START WITH POWER SUPPLY OFF!

Follow these steps for first start-up:

Open the TMCL-IDE and connect the Landungsbruecke via USB to the computer.
Verify that the Landungsbruecke is using the latest firmware version.
Arrange the main window related to your needs. We recommend using full screen and opening up the Register Browser.
The TMCL-IDE includes a dialogue for diagnostic tasks. Further, the dialogue provides an overview of the connected motion controller and driver chips.

Hardware Information

All design files for the evaluation boards are available for free. The original ECAD files (Eagle, Altium, or PADS), Gerber data, the BOM, and PDF copies can be downloaded from the TRINAMIC Eval Kit homepage. Please check schematics for Jumper settings and input/output connector description.

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 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 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 overview of the connected motion controller and driver chips. 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 (Eagle, Altium, or PADS), Gerber data, the BOM, and PDF copies. 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.

Onboard Jumpers
The TMC2300-Eval board has two jumpers on the top left side to select the Step/Direction source. The internal source uses the MCU to generate steps, the external source uses the external Step/Direction pin header in the lower right corner

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 using the wizards. Note In order to achieve good settings please refer to descriptions and flowcharts in the TMC2300-LA datasheet. The register browser of the TMCL-IDE provides helpful information about any currently selected parameter. Beyond that, the datasheet 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 browser window when using the velocity graph.

FIG-5 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.

ChipClick
To configure the control pins for the TMC2300-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.

CoolStep™ Tuning
With the TMCL IDE and the EVAL-KIT you have a powerful tool to find your CoolStep™ to run your motor most energy efficient and cool. To tune it, please open the CoolStep™ & StallGuard2™ window you’ll find on the left of the IDE when you have connected the EVAL board. On the CoolStep™ tab you will see below picture by default.

FIG-8

CoolStep™ will get activated as soon as you change the “Hysteresis start” value higher than 0 and enter a “Threshold speed” value higher than 0.

FIG-9

The above values activate CoolStep™ but the values can be fine tuned to make CoolStep™ work reliable and in a way as you need it in your application. For that it is important to understand what each setting is doing.

Current minimum : The current minimum setting will be the lowest current when CoolStep™ is activated. With 1A RMS the current will either be reduced to a quarter or to the half of this current when no or less force is applied to the motor shaft.
Current down step : Current down steps defines the speed of the current to drop down after load gets released from the motor shaft.
Current up step : This setting defines the step height when hitting the lower StallGuard2™ threshold (Hysteresis start).
Hysteresis width : This setting defines the area of the StallGuard2™ threshold (Hysteresis end).
Hysteresis start : This setting defines the switching point, related to the StallGuard2™ value, to boost up the current by one step.
