Activating the data management frame
Data management frames can be written in the part program and via the user interface of SINUMERIK Operate.
The following should be noted when activating the data management frames in the channels written directly and
via frame mapping:
• Writing in the part program
The data management frames must be explicitly activated in each channel (G500, G54 ... G599)
• Writing via user interface
Data management frames are written via the user interface – e.g. by entering new work offsets. A modified
data management frame is immediately active in all of the involved channels if none of these channels is in
the "Channel active" state. The data management frame is not active in any channel if one of the channels
involved is in the "Channel active" state. The activation must then be explicitly programmed in each channel in
the part program (G500, G54 ... G599). Or, the next time that the channel state changes, it becomes active
after "Channel reset".
Example
The following channels and channel axes are parameterized at a control:
• Channel 1
- Z: Geometry axis
- AX1: Machine axis of geometry axis Z
• Channel 2
- Z: Geometry axis
- AX4: Machine axis of geometry axis Z
The zero point of the Z axis should always be the same in both channels:
• Mapping relationship: $MA_MAPPED_FRAME[AX1] = "AX4"
