Possible problems
Can lead to
Poor cable connections
Loss of backlight, video signal, overlay function, and/or LCD power. Check
all cable connections.
Overlay Key failure
Keys on panel do not work. Check by using service code 81. The screen will
display a picture of the overlay. Each key pressed on the overlay will light
up on the screen and the pendant will beep which means it is working. If
not check the connections between the Program panel overlay and the
overlay interface board. Also check the overlay power cable for the critical
keys and COM port cable for all other keys. Refer to Fig. 5.4b.
LCD has no display
You will not have the ability to see the video signal. Make sure the user
interface board is not turned off (figure 5.4c). If the user interface board
LED is on but the backlights remain off. Check all cable connections to LCD
controller board and inverter board. See Fig. 5.4b.
Electronic Handwheel does
not work
Unable to jog an axis. Make certain that the jog speed key you want is
pressed and you have selected the axis you wish to move. Check service
code 132 to verify EHW is counting. One complete revolution of the EHW
will display 100 counts on the screen. If not check EHW cable connection at
the rear of panel to the computer module. You can also verify the
computer module is reading the EHW signals but looking at the LED lights
on the front of the computer module. See section 5.3 for more info.
Faulty E-stop switch
Unable to clear the E-stop and reset the E-stop safety relay – replace the
switch.

of 9,600 ppr (38,400 counts per revolution). The motor encoder also contains one index pulse per
