mode
The most recently set speed stays active until a power
interruption. After the control has been started, the speed
is set to MAX.
After you have started a program, the control displays the following
soft keys with which you can set the simulation speed:
Soft key Functions
Test the NC program with the speed that will
be used when actually running the program
(programmed feed rates will be taken into
account)
Increase the simulation speed incrementally
Decrease the simulation speed incrementally
Test run at the maximum possible speed
(default setting)
You can also set the simulation speed before you start a program:
Select the function for setting the simulation
speed
Select the desired function by soft key, e.g.
incrementally increasing the simulation speed
Repeating graphic simulation
A part program can be graphically simulated as often as desired. To
do so you can reset the graphic to the workpiece blank.
Soft key Function
Show the unmachined workpiece blank
