6.10 Program run

Application

In the Program run, full sequence operating mode, the control
executes an NC program continuously to its end or up to a program
stop.
In the Program run, single block operating mode, the control
executes each NC block individually after pressing the NC Start key.
With point pattern cycles and CYCL CALL PAT, the control stops
after each point. The workpiece blank definition will be interpreted as
a separate NC block.
You can use the following control functions in the Program run,
single block and Program run, full sequence operating modes:
Interrupt program run
Start the program run from a certain NC block
Skip NC blocks
Edit the tool table TOOL.T
Edit the active datum table or compensation table
Checking and changing Q parameters
Superimpose handwheel positioning
Functions for graphic simulation
Additional status display
Caution: Danger due to manipulated files!
If you execute NC programs directly from a network drive or a USB
device, you have no control over whether the NC program has
been changed or manipulated. In addition, the network speed can
slow down the execution of the NC program. Undesirable machine
movements or collisions may result.
Copy the NC program and all called files to the TNC: drive
