Error 3002 · CNC 8055 M · CNC 8055 T
Message: WATCHDOG in the periodic module (PE).
Detection
Any time.
Effect
It stops the movement of the axes and the spindle, eliminating all the enable signals and canceling all the analog outputs of the CNC. When detected from the position loop, it opens the position loop and sets the LOPEN mark to ·1·.
If it is in execution, it interrupts the execution of the part program of the CNC of all channels.
Besides this, it activates the external emergency output.
Cause
The possible causes are:
- The execution of the PLC’s periodic program has exceeded the time set in PLC parameter WAGPER(P1).
- The program is in an endless loop.
Solution
Increase the time of PLC parameter WAGPER(P1) or increase the PLC speed.
Insert CPU TURBO. Change PLC parameter CPUTIME(P26) or general parameter LOOPTIME(P72).
