Extended superimposed control of PMC
axis

Explanation
Command which can run continuously
● The block with no motion. (e.g. block of auxiliary function, dwell, O/N number,
EOB, and so on)
● The cutting feed block.
● The rapid traverse block with no command of superimposed axis.
Command which waits until the end of PMC axis moving
● The rapid traverse block with command of superimposed axis.
● The block of G05, G05.1, G08.
There above CNC blocks are started after stopping the PMC axis moving.
The rapid traverse and cutting feed are different in many elements such as acc./dec.
type, feed-forward state and so on. Therefore the rapid traverse and cutting feed can not
superimpose. Because the feed-forward state is changed in the block with G05, G05.1,
G08, the CNC program can not run continuously.
Notice
● If this extended function is enable, the advanced feed-forward state and off state
are according to the CNC axis state during superimposed control. Therefore the
parameter G8C, G8R (No.8004#3, #4) which decided to enable/disable "look-
ahead control" in PMC axis is disable.
● The advanced feed-forward state is selected according to the CNC parameter
setting at the start of superimposed control during the axes stop (e.g. reset state,
feed hold state, and so on).
When the PMC axis is started superimposed control (cutting feed) in reset state,
the feed-forward state is decided to enable/disable by the parameter FFD
(No.2005#1) .
When the PMC axis is started superimposed control (cutting feed) in feed hold
sate in look-ahead control mode, the advanced feed-forward state is enable.
● Do not change the superimposed control states (signal EASIPx) during moving.
