Program simulation and execution.
4.3.3 Execute a program.
The name of the program selected in the channel for execution appears on the general status
bar. If not indicated otherwise, the program execution will begin from the first block of the
program to the execution of one of the end-of-program functions "M02" or "M30". As an
option, it is possible to define the first and last blocks of the execution. See "4.3.2 Select the
first and last blocks of the execution." on page 74.
Start executing
To start the execution of the program, press [START] on the Operator Panel.
The program may be executed in –single block– or –automatic– mode; the mode may be
selected even while executing the program. When –single block– is active, the screen will
display the relevant symbol on the general status bar.
If the –single block– mode is active, program execution will be interrupted at the end of each
block; the [START] key must be pressed again to execute the next block. If the –automatic–
mode is active, the program will be executed all the way to the end or up to the block selected
as end of execution.
Interrupting the execution
The [STOP] key interrupts the execution of the program. Press [START] again to resume
execution from where it was interrupted.
The execution may be interrupted at any time, except when threading. In that case, it will be
interrupted at the end of the threading operation.
Stop the execution
The [RESET] key cancels the execution of the program and resets the CNC to its initial
conditions.
Activate rapid traverse while executing a program.
If the OEM has set it this way (parameter RAPIDEN), while executing the program it will be
possible to apply rapid traverse to programmed movements (except to G00 movements and
to threading operations). Depending on how this option has been configured, rapid traverse
may be applied from the PLC (for example using user keys) or with the "rapid" key of the jog
panel or, on the other hand, it may be necessary to use both.
The feedrate for these movements is set by the FRAPIDEN parameters of the axes and of
the channel. If these parameters are set to zero, the CNC does not limit the feedrate and
assumes the one set for G00. The feedrate cannot exceed the maximum feedrate set by PLC
(variable (V.)PLC.G00FEED), but it can exceed the maximum machining feedrate
(parameter MAXFEED of the axes and of the channel) and the active feedrate set by PLC
(variable (V.)PLC.F).
When pressing [START], the CNC saves the program being edited, even if the programs being edited
and executed are different.
Every time [START] is pressed, the CNC checks that the room temperature does not exceed 65 ºC
(149 ºF) and, if it does, the CNC does not let run the program and issues the corresponding error
message.
The program selected for execution may be executed in any operating mode by pressing [START] on
the Operator Panel. The CNC will request confirmation before starting to execute the program.
When only one of the two options is necessary to activate rapid traverse and the CNC has several
channels, activating rapid traverse from the PLC only affects the corresponding channel. The rapid key,
on the other hand, affects simultaneously all the channels that may be affected at the time. If the active
channel is in jog mode and another channel is executing a program, when pressing the rapid key in
the active channel (jog mode), the rapid traverse will also be applied in the channel that is executing
the program.
