* Note on axis replacement
This replacement of a "neutral axis" by an "NC program axis" does not take place until the
PLC has really relinquished control of the axis in accordance with use case "Relinquish
control of axis". Waiting for this axis interchange is displayed on the HMI operator panel
front.

cannot be requested for the NC program. GET or
AXTOCHAN from the NC program or a
synchronized action, or programming the axis in
the NC program, are rejected with alarm 26075.
For the PLC-controlled axis
channel-specific
IS DB 21, ... DBX6.0 ("feed disable") is not
effective. This axis is not stopped when feed
disable is activated, but continues to move.
the axis is not taken into account when
IS DB 21, ... DBX36.3 ("all axes stationary") is
generated. This signal is output with 1 even if all
other axes in the channel are stationary and only
the PLC-controlled axis is active.
