4.1 Building up serial communication
For correct communication data setting, proceed as follows:
1. Completely connect the 931E/K servo positioning controller.
2. Use a serial cable to connect the free interface of your PC with the 931E/K servo
positioning controller.
3. Switch on the control voltage (24VDC).
4. Start the parameterisation program
If the Online button is highlighted in green in the button menu (see figure), the
communication parameters have been set correctly.
If the parameterisation program cannot open the serial interface, the following error
window will appear when the program is started:
931e_202
Cause of the error will either be an incorrect interface setting (check the hardware settings
in your control panel) or another Windows or DOS−program accessing the serial interface.
