In all views, a clock is displayed during graphical processing. The machining time is displayed
in hours, minutes and seconds. It is approximately equal to the time that the program requires
for processing including the tool change.
Determining the program runtime
The program runtime is determined when executing the simulation. The program runtime is
displayed in the editor untíl the next program change at the end of the program.
Properties of simultaneous recording and simulation
Traversing paths
In simulation, the traversing paths displayed are saved in a ring buffer. If this buffer is full, then
the oldest traversing path is deleted with each new traversing path.
Optimum display
If simultaneous machining is stopped or has been completed, the display is again converted
into a high-resolution image. In some cases, this is not possible. In such cases, the following
message is output: "High-resolution image cannot be generated".
Working zone limitation
No working area limitations and software limit switches are effective in the tool simulation.
Start position for simulation and simultaneous recording
During simulation, the start position is converted to the workpiece coordinate system by
application of the zero offset.
The simultaneous recording starts at the position at which the machine is currently located.
Restrictions
● Traori: 5-axis motion is linearly interpolated. More complex motion cannot be displayed.
● Referencing: G74 from a program run does not function.
● Alarm 15110 "REORG block not possible" is not displayed.
● Compile cycles are only partly supported.
● No PLC support.
● Axis containers are not supported.
Supplementary conditions
● All of the existing data records (Toolcarrier / TRAORI, TRACYL) are evaluated and must
be correctly commissioned for correct simulation.
● Transformations with swiveled linear axis (TRAORI 64 - 69) as well as OEM transformations
(TRAORI 4096 - 4098) are not supported.
