Steps to take.
1, Turn the power onto the system.
2, Press the control on button.
3, what do you see happen on the 600V power supply LED display?
E.G. 0 then 2 then back to 1, or do you see a different number.
4, what stage will the software boot up to before the error?
E.G. phase 1, phase 2, phase 3 or when the CNC is compiling the PLC’s.
Have you checked all the power in the system?
Check that the 24V power supply is working.
Check all the breakers in the system. Turn them off and back on please.
More checks that need to be made? As one of the photos has front panel not being detected?
Please check the watchdog with the following procedure:
1. Identify the watchdog LED. There are 3 LEDs in the top right corner of the front panel controller. The watchdog LED is the one closest to the corner. It is labeled “watchdog” in small print.
2. Start with the power turned off. The LED should be off.
3. Turn the machine power on. The LED should still be off.
4. Reset/enable the machine. The LED should flash on and then off several times (about 1 second each).
5. If error reset was successful the LED will stay on.
Please let us know the results. If possible, we would like to see a video of the LED during this procedure.
If the LED never comes on then please replace the front panel PCB.
If there is some other behavior of the LED then check:
1. All armature cable shields are firmly terminated to the gear tray.
2. The black cable running from the front panel controller to the safety unit is not routed near any noisy cables such as mains cables or armature cables.
If all the software loads correctly and the error only happens when they press the reset button.
