3.5.2 SINGLE BLOCK EXECUTION
When operating in Single-Block mode, the CNC ignores function G05 and executes all
the movements as if they were programmed in G07.
The CNC considers the execution of the block concluded when all the involved axes have
reached position. In other words, when all their "In-Position" outputs are high.
If while executing a G05 in Automatic mode, you switch to Single Block mode, the CNC
will execute this block in G07 and it will generate the "Brake" and "In-Position" signals
at the end of the block.
3.5.3 MANUAL FEEDRATE OVERRIDE SWITCH
When selecting any position between 4% and 120% of the
%Feed area, the Fast/Slow sequence will be the one
described earlier.
When selecting the 2% position of the %Feed area, the
CNC always applies the "Slow " feed.
In other words, if while being the "Fast" output active, the
2% position is selected, the CNC cancels the "Fast" output
and it activates the "Slow" output, instead.
When selecting the 0% position of the %Feed area, any JOG position or any Handwheel
position (
), the CNC will stop the axes cancelling the "Fast" and "Slow" outputs. It
does not change the status of the "Brake" and "In-Position" outputs.
3.5.4 CYCLE STOP AND FEEDHOLD SIGNALS
Whenever the key is pressed, the "Cycle Stop" input is set low (pin 16 of connector
I/O1 to 0V) or the Feedhold input is set low (pin 15 of connector I/O1 to 0V), the CNC
behaves as follows:
* It stops the axes cancelling the "Fast" and "Slow" outputs.
* It does not change the status of the "Brake" and "In-Position" outputs.
If the Feedhold input was set low, when setting it back high, the "Fast" and "Slow" signals
will recover their previous status.
