Operating modes
The CNC distinguishes between five operating modes. It is possible to switch over between these operating modes via the operator-control and/or PLC interface, whereby only one operating mode may be active at any one time.
The following operating modes are define:
Operating mode | ST-Constant | Value | Description |
---|---|---|---|
Standby | GCW_250_HLIImcmStandbyMode | 1 | No operating mode is selected. Default after starting the control. |
Automatic | GCW_250_HLIImcmAutomaticMode | 2 | The control can run a complete NC program automatically. In this case, program execution can be interrupted and resumed. |
Manual-Block | GCW_250_HLIImcmMDIMode | 3 | Movements are commanded by the operator-control computer via a single NC block. The NC block is transferred as a string to the control and executed via a START command. Interruption and resumption of movement are possible in this case. |
Manual mode | GCW_250_HLIImcmManualMode | 4 | Movements are commanded by peripherals connected directly to the control (keys, handwheels). |
Homing | GCW_250_HLIImcmReferenceMode | 5 | The axes can be referenced. An NC program of name rpf.nc is started in this case. |
An operating mode may have different states. The states of the individual operating modes and their significance in respect of the operating mode are discussed in the Chapters which follow.
