19.5.1 Changing start sequences
With the rotary switch on the HSSB board on the CNC side (when the CNC
does not have the PC function) or on the motherboard of the CNC (when the
CNC has the PC function), the start sequence can be changed.
Position 0 can be selected as required to perform maintenance using the
boot and IPL screens.
Position 0 (maintenance)
1. Wait until communication with the CNC is established.
2. Display the boot screen.
3. Display the IPL screen.
4. Display the CNC power–on screen.
5. Initialize the work area for the data window library.
6. Start a registered application program.
7. Perform monitoring for communication errors and CNC system alarms.
Position 1 (normal operation)
1. Wait until communication with the CNC is established.
2. Initialize the work area for the data window library.
3. Start a registered application program.
4. Perform monitoring for communication errors and CNC system alarms.
Position 2 (asynchronous start)
1. The CNC starts without waiting for communication to be established.
2. After communication is established, the PC performs initialization
described below.
3. Initialize the work area for the data window library.
4. Start a registered application program.
5. Perform monitoring for communication errors and CNC system alarms.
