1 Features
The TMC262 evaluation board features a TMC262 with external power MOSFETs plus a
microcontroller, which allows interfacing to a PC for visualization and control of all parameters. The
motor can be operated via the step and direction interface both, using an external source, and using
the integrated microcontroller as a step generator.
Highlights
Evaluate all features of the TMC262
Use stallGuard2™ with your motor
Use coolStep™ with your motor
Control all parameters from a PC using special software or TMCL-PC
Motor current can be set to up to 1A, 2A or up to 4A (soldering jumper) via on-board sense
resistors
Supply voltage up to 40V (MOSFETs can be exchanged against 60V 2A types)
Access all pins of the TMC262
Motor type
2 phase Stepper

3.3V regulator figure 1: application block diagram as realized on TMC262-EVAL The TMC262-EVAL board features the TMC262 plus a microcontroller, which realizes an interface to a 3.1 Power driver stage The power MOSFETs on resistance mainly influences the current and voltage capability of the board. -
Page 4: Sense Resistors And Current Setting
There are optional filter components designed in on the board. These allow experimenting with EME filters, e.g. RC and LC filter with RC dampening. Please see the board schematic for sample values. Copyright © 2010 TRINAMIC Motion Control GmbH & Co. KG... -
Page 5: Board Pinning
Attention: Do not pull or plug the motor connector during operation, as inductive spikes could destroy the driver. First disable the driver (there is a button in the Eval software) or switch off the power supply. Copyright © 2010 TRINAMIC Motion Control GmbH & Co. KG... -

Page 9: Getting Started
In case you want faster motion, stop the motor, go to the tab DRVCTRL and reduce microstep resolution. Best performance is achieved in 256 times microstepping, or in 16 times microstepping with step interpolation active (please check INTPOL). Copyright © 2010 TRINAMIC Motion Control GmbH & Co. KG... -

SEUP and SEDN. You can select, if the current becomes scaled down to ½ of CS or to ¼ of CS, using SEIMIN setting. For details and sample traces, please see the TMC262 data sheet. Copyright © 2010 TRINAMIC Motion Control GmbH & Co. KG... -
Page 11: Optimizing The Chopper Settings
In order to transfer the settings into your own software, there is a C language export function. This will write out the initialization values for the TMC262 in a C syntax form, which allows easy sending via a microcontroller SPI interface. Copyright © 2010 TRINAMIC Motion Control GmbH & Co. KG... -
Page 12: Tmcl Commands
You can use the direct mode of the TMCL-IDE to explore it, or remote control the module with TMCL-PC in order to drive sequences. The address of the TMC262-EVAL is always fixed 1. The board supports a number of SAP and GAP commands in order to set parameters. - Page 13 208: error bits of read back data 8: 1=target position reached, 0=target position not reached. Parameters 0,1,2,3,4,5,8 and 181 are not directly coupled to TMC262 but are connected to the software ramp generator in the microcontroller. Copyright © 2010 TRINAMIC Motion Control GmbH & Co. KG...
