Changeover sequence

Access to axes

If output of the channel is not suspended, the physical axes are linked to the logical axes of the channel. If a second channel requests the same physical axis as that of the first channel, the system waits until the first channel has suspended its output.

When axis access is enabled, any axis movement is first stopped by an implicit feed rate stop.

Changeover sequence 1:

Changeover sequence 2:

If access to one physical axis by two (or several) channels is configured, a channel is not given access to the axes until all other channels have suspended their access (suspend_channel_output = TRUE).
