5 Functional Description
5.1 Typical Application Wiring
Wire the TMCM-1070 as shown in the following figures.
• Connect the the power supply to V+ and GND.
• Connect the Step and Direction signals to your motion controller.
• At power up time, the EN input must be low (= driver stage disabled)!
• Optional: Connect UART to a TTL UART interface with 5V logic levels. To configure your TMCM-1070
connect start the TMCL-IDE and use the parameterization tools. For detailed instructions refer to the
TMCM-1070-firmware-manual.
Note
The TTL UART interface is not optically isolated. It has and requires 5V level
signals.
Nevertheless, it provides basic ESD and rail-to-rail signal line protection for the
TMCM-1070.
