12.1.8 Self-diagnosis
General
If a failure occurs, it is first necessary to check whether the failure has
originated in the CNC, PMC, or machine, in order to perform quick
troubleshooting.
In some external signal wait states or the like, the operation of the
machine may stop as if a failure had occurred. In this case, the status of
the CNC-PMC interface or CNC-machine interface and the internal
status of the CNC must be checked.
The CNC checks for the following during operation:
1 Error in the detection system
2 Error in the position control unit
3 Error in the servo system
4 Overheating
5 CPU error
6 ROM error
7 RAM error
8 Error in program memory
10 Data input error
11 Error in data transfer to and from the PMC
In addition, the CNC checks the input/output signals transferred
between the PMC and CNC and the internal CNC status. These
statuses can be displayed on the screen.
