Superimposition
- Specification
When an axis is moving by controlling as PMC-axis, it is possible to command to that axis
from execution program. And it is possible to command to an axis at program execution from
PMC side. By this, CNC axis command and PMC axis command can be superimposed.
- Axis control superimposition signal
#7 #6 #5 #4 #3 #2 #1 #0

[Classification] Input signal
[Function] By setting the corresponding bit to “1” for the axis which need to be superimposed, CNC axis
command and PMC axis command can be superimposed.
Superimposition is executed on the following condition.
CNC axis : Cutting feed mode with incremental command
PMC axis : Cutting feed mode
In case of other conditions, the alarm 130 is generated.
(Note 1) The cutting feed command on CNC side must be incremental command.
(Note 2) When axis control superimposition signal is set to “0” during an axis is moving with
superimposed state, the alarm 130 is generated. Please confirm that an axis stops
when axis control superimposition signal is set to “0”.
(Note 3) If the sum of CNC axis pulses and PMC axis pulses is too large at superimposition,
the alarm 138 is generated.
- Command which can run continuously
When the following block is commanded during program execution, the block is executed
without waiting superimposed command end from PMC.
Block with no motion (e.g. block of auxiliary function, dwell, O/N number, EOB and so
on)
Cutting feed block
Rapid traverse block with no command of superimposed axis
