NCU global basic frames
For rotary indexing machine technology, for example, a channel must be used to define
frames for other channels. These cross-channel frames are shown in the "NCU global basic
frames" below.
Properties of the NCU global basic frames:
• Can be read and written from all channels.
• Can be activated only in the channels
• There are up to 16 NCU global basic frames
Global frames can be used to apply offsets, scale factors and mirroring operations to
channel and machine axes.
All basic frames (up to 16 global and 16 channel-specific) are chained to produce total basic
frame. The standard configuration is designed in such a way that there is at least one basic
frame per channel.
Settable frames can be defined as either NCU global or channelspecific.
Channel coordination
With NCU global frames, the user must ensure channel coordination and activation of the
frames (e.g. using the WAITMC command), to allow the frames to be calculated at the
desired point in the program.
Crosschannel activation of frames is not supported.
