When the system detects a condition that prevents the system from maintaining normal operation, the system alarm screen will be transferred. When entering the system alarm state, the system will:
- Disconnect the excitation of servo and spindle amplifier
- Disconnect I/O Link communication
When a system alarm occurs, it switches to the screen shown below. This screen is called the system alarm screen.
System alarms can be categorized into the following three types.
- Alarms detected by software
- Alarms detected by hardware
- Other alarms
1 Alarms detected by software
Alarms detected by software
Software abnormalities are detected mainly by the CNC system software. Typical causes of abnormalities are:
- Detection of processing/data conflicts based on internal status monitoring software
- Access outside the data/command range
- Divide by zero
- Stack overflow
- Stack overflow
- DRAM sum check error
2
Alarms Detected by Hardware
Hardware anomalies are detected primarily by the hardware. Typical causes of anomalies are:
- Parity error (DRAM, SRAM, Hyper Cache)
- Bus error
- Power alarms
- FSSB cable disconnection
3
Other Alarms
Other causes are:
- Alarms detected by peripheral software
- Servo software (watchdog, etc.)
- PMC software (I/O Link communication abnormality, etc.) |
