2.1 First Start-Up
1. Make sure that the latest version of the TMCL-IDE 3.X is installed. The TMCL-IDE can be downloaded
from www.trinamic.com/support/software/tmcl-ide/.
2. Open the TMCL-IDE and connect the Landungsbruecke via USB to the computer. For Windows 8 and
higher no driver is needed, on Windows 7 machines the TMCL-IDE is installing the driver automati-
cally.
3. Verify that the Landungsbruecke is using the latest firmware version. The firmware version is shown
in the connected device tree. The newest firmware can be downloaded from
www.trinamic.com/support/eval-kits/details/landungsbruecke/.
Figure 2: Firmware Version
4. The TMCL-IDE 3.X 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.
5. 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.

3 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 our homepage: TRINAMIC
Eval Kit homepage.
Note If files are missing on the website or something is wrong please send us a note.
3.1 Power connector
The TMC5272-EVAL has the option to use two power inputs. You need to use both if you want to use the
TMC5272 at low voltages. This is necessary as the Landungsbruecke needs a minimum voltage of 8 V via
the Eselsbruecke connector to operate correctly.
Connector J202 (right in figure 5) is the main connector to power the TMC5272-EVAL-KIT. If the TMC5272
should be evaluated at voltages below 8 V a second supply needs to be attached via J203 (left in figure 5).
Please refer to chapter 3.1.2 in this case.

3.1.2 Dual supply
By using two supplies, the full voltage range of TMC5272 can be used.
•+VM (J202) = 2.1. . . 20 V
•+VL (J203) = 8. . . 28 V
3.2 Voltage selection
In case the TMC5272 VIO should be used with +5 V instead of +3.3 V there is a solder selection near the
EEPROM. This selection should be changed, if a external electronic with 5 V levels is connected.
Using the TMC5272-EVAL with Landungsbruecke, the VCCIO must be set to +3.3 V (default).
NOTICE Don’t bridge both selections at the same time. This might disturb the onboard
voltage regulator. Leave at +3.3 V (default) in combination with Landungsbruecke.

3.3 Onboard Connectors
The TMC5272-EVAL has 7 onboard connectors. The following table contains information on the connector

4 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 TMC5272 data sheet. The register browser of the TMCL-IDE provides help-
ful 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 appli-
cation. 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.
4.1 Current Settings
To configure the current settings for the TMC5272-EVAL, open the TMC5272 Current Settings tool by click-
ing the appropriate entry in the tool tree. This tool usually includes settings to control the IC registers
and selecting the reference resistor via Landungsbruecke. It is recommended to use this tool first. Newer
generations of ICs provide a wide range of current settings. Therefore the tool might look different or
support other functionalities.

4.2 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. You might have to change the desired
run and hold currents in Current Settings tool before.
Note In order to get a more accurate graphical velocity view, close the register browser
window when using the velocity graph.

4.3 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 ad-
justed here.
Open the position graph tool to get a graphical view of the actual position. You might have to change the
desired run and hold currents in Current Settings tool before.
Note In order to get a more accurate graphical position view, close the register browser
window when using the position graph.

4.4 StallGuard4 Tuning
To tune StallGuard4 properly you need to set the current for the motor first, e.g. 1A RMS. After that you
specify the velocity to run the motor with. This could be 75 rpm as in this example. You can use the
TMCL IDE to calculate the velocity with the "Parameter calculator" tool shown in the list on the left when
connecting the board.
Figure 13: TMCL IDE v3.0.20.0 Parameter calculator
In the TMCL IDE you can use the CoolStep & StallGuard4 graph where the StallGuard4 value is shown
in blue. There are two parameters that need tuning for proper StallGuard4 use. StallGuard4 Threshold
(SGT), will need to be tuned by raising or lowering the SGT value. The goal of SGT it so have it hit 0 before
a stall occurs. If the SGT is too high, a step loss will occur and you need to lower it. In the picture you see
two regions. In the first region the SGT value was too high. It was set to 10 and with loading the motor
you can see the value does not reach 0. In the second region the SGT value was set to 4 which results in
hitting the 0 axis just short before the motor stalls.
Figure 14: CoolStep & StallGuard4 window
With optimal StallGuard4 settings you can optionally activate CoolStep.

4.5 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 or StallGuard4 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.
Figure 15: CoolStep & StallGuard2 (or StallGuard4 ) window
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.

Figure 16: CoolStep & StallGuard2 (or StallGuard4 ) window
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 acti-
vated. 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 or Stall-
Guard4 threshold (Hysteresis start).
•Hysteresis width: This setting defines the area of the StallGuard2 or StallGuard4 threshold (Hys-
teresis end).
•Hysteresis start: This setting defines the switching point, related to the StallGuard2 or StallGuard4
value, to boost up the current by one step.
