Load monitoring G996
G996 defines the type of load monitoring or deactivates the load
monitoring temporarily.
Activate direct program-run continuation G999
With the G999 function, when running a program in Single Block
mode, the following NC blocks are run with a single NC start to the
end of the program. G999 is then deactivated by again calling the
function with the setting Q=0 (off).
Converting and mirroring G30
The G30 function converts G codes, M functions and spindle
numbers. G30 mirrors traverse paths and tool dimensions and shifts
the machine zero point about the "zero point offset" of the axis
(machine parameter: Trans_Z1).
Application: For full-surface machining, you describe the complete
contour, machine the front face, rechuck the workpiece through an
expert program and then machine the rear face. To enable you to

Parameters
Q
Lib. switch (type of activation): Monitoring (default: 0)
 0: Off
 1: G0 Off (do not monitor rapid traverse)
 2: G0 On (monitor rapid traverse)
Q Monitoring: Type of load monitoring (default: 0)
 0: Utilization + Total utilization
 1: Utilization only
 2: Total utilization only
In addition to defining the type of load monitoring with
G996, you need to specify the monitoring zone with G995
(see „Monitoring zone G995” on page 388).
Before using the load monitoring feature, you also need to
define limit values and perform reference machining (see
User's Manual).
Parameters
H Table number of the conversion table (possible only if the
machine tool builder has configured a conversion table).
Q Spindle number
