Setting the LCD Panel ID:
There is an EEPROM
in the inverter, which store its supported LCD type and ID
code. If you replace the LCD with one of a different brand,
the ID information in the inverter EEPROM should be
updated.
Follow the steps below to set the LCD inverter ID:
1. Boot from the Maintenance Program Diskette.
2. Select Panel ID Diagnostic from PC DOS 7.0 Startup
Menu.
3. Follow the instructions on the screen to read the
current ID Code or to set a new inverter ID code.
Note: When you set a new inverter ID and the new
LCD is not yet enabled (to function), connect
an external CRT to see the program execution
process.
Attention: Make sure that the new ID code you
choose corresponds to the LCD brand and type. If
you write a wrong ID into the inverter, just reboot and
re-execute the program and input the correct ID code.
4. Restart the computer — the new LCD should work
normally.
