Product Usage Instructions
Getting Started
You need:
- The latest version of the TMCL-IDE software installed. It can be downloaded from www.trinamic.com/support/software/tmcl-ide/.
- The Landungsbruecke or Startrampe connected to the computer viaUSB.
- Verify that the Landungsbruecke or Startrampe is using the latest firmware version.
Precautions:
Figure 1: Getting started
NOTICE: The Landungsbruecke operates on USB Power Supply. All other voltages are generated from V_M. The kit works only when V_M is applied.
First Start-Up
-
Make sure that the latest version of the TMCL-IDE 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, no driver is needed. On Windows 7 machines, the TMCL-IDE automatically installs the driver.
-
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 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. Thus, a window pops up immediately after connecting the evaluation kit for 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.

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
fiowcharts in the TMC2590-TA 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 browser window when using the velocity graph.
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.
StallGuard2™ Tuning
To tune StallGuard2™ 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.
In the TMCL IDE you can use the CoolStep™ & StallGuard2™ graph where the StallGuard2™ value is shown in blue. There are two parameters that need tuning for proper StallGuard2™ use. StallGuard2™ 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.
With optimal StallGuard2™ settings you can optionally activate CoolStep™.
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 eficient 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.
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.
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™ or Stall- Guard4™ threshold (Hysteresis start).
- Hysteresis width: This setting defines the area of the StallGuard2™ or StallGuard4™ threshold (Hysteresis end).
- Hysteresis start: This setting defines the switching point, related to the StallGuard2™or StallGuard4™ value, to boost up the current by one step.
