6. Connect the power supply as follows:
Pin
Label
Description
1
+U
Module and driver stage power supply input
2
GND
Module ground (power supply and signal
ground)
Please note, that there is no protection against reverse polarity and only limited protection
against voltages above the upper maximum limit. The power supply typically should be within
a range of +12 to +28.5V.
When using supply voltages near the upper limit, a regulated power supply is mandatory. Please
ensure that enough power filtering capacitors are available in the system (2200µF or more
recommended) in order to absorb energy fed back by the motor while the motor is decelerating and
in order to prevent any voltage surge e.g. during power-on (especially with longer power supply
cables as there are only ceramic filter capacitors on-board). In larger systems an additional external
zener/suppressor diode with adequate voltage rating might be necessary in order to limit the
maximum voltage.
To ensure reliable operation of the unit, the power supply has to have a sufficient output capacitor
and the supply cables should have a low resistance, so that the chopper operation does not lead to
an increased power supply ripple directly at the unit. Power supply ripple due to the chopper
operation should be kept at a maximum of a few 100mV
7. Switch ON the power supply
The power LED glows now. If this does not occur, switch power OFF and check your connections as
well as the power supply.
8. Start the TMCL-IDE software development environment
The TMCL-IDE is available on www.trinamic.com.
Installing the TMCL-IDE
Make sure the COM port you intend to use is not blocked by another program.
Open TMCL-IDE by clicking TMCL.exe.
PROCEED AS FOLLOWS:
Choose Setup and Options as shown in Figure 3.1.
Choose the Connection tab.
Choose Type.
The TMCL-IDE shows you which Port the module uses.
Click OK.
GUIDELINES FOR POWER SUPPLY:
a) keep power supply cables as short as possible
b) use cables with large diameters for power supply cables
c) add 2200µF or larger filter capacitors near the motor driver unit especially if the distance to
the power supply is large (i.e. more than 2-3m)
