18. PC Graphical User Interface

The User Interface is easily installed via the CD-ROM installer. The PC Interface is using the optically isolated USB

connection to powered the board and communicate with it.

Once the Motor Control PC GUI is installed based on the explanations of the Quick Start Guide, please click on the

“Speed Control” button to display the following window:

Please find below the description of the Alarm codes coming from the PC GUI:

Alarm 1:

The alarm 1 is called “EEPROM alarm” and described in the software by “EQP_ALL”. This alarm is set when one or

more EEPROM parameters are higher than the maximum allowed value or lower than the minimum allowed value.

The LED DL4 is quickly blinking on the main board to indicate that an alarm is set.

The maximum and minimum values are specified in the two constants tables called: "par_max[]" "par_min[]" in the

"ges_eqp.h" header file. Another root cause for the alarm 1 is the EEPROM hardware failure when the error is

accessed in read or write mode.

When this alarm is active, the access to the EEPROM is restricted. To reset the alarm the default parameters set

should be reloaded in the EEPROM. By using the PC GUI and the parameters setting window, it becomes possible to

clean the EEPROM content. The first step is to write the magic number “33” in the first parameter n°00. The second

step is to reset the board by pressing the reset button on the PCB or switching off the power supply.

At this point a coherent set of parameters is loaded and the alarm should disappear.

Finally, if the alarm is produced by a hardware failure of the EEPROM itself, then the board needs to be repaired
