TMC2590-EVAL Evaluation Board • Document Revision V1.0 • 2019-AUGUST-16 1.1 4 / 11 First Start-Up 1. 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/. 2. 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. 3.

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.

TMC2590-EVAL Evaluation Board • Document Revision V1.0 • 2019-AUGUST-16 3.3 8 / 11 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. Figure 6: TMCL IDE v3.0.20.

TMC2590-EVAL Evaluation Board • Document Revision V1.0 • 2019-AUGUST-16 3.4 9 / 11 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. Figure 8: TMCL IDE v3.0.20.

TMC2590-EVAL Evaluation Board • Document Revision V1.0 • 2019-AUGUST-16 10 / 11 Figure 9: CoolStep™ & StallGuard2™ 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 activated.
