Speed of the Setting test runs
The most recently set speed stays active until a
power interruption. After the control is switched on
the speed is set to FMAX.
After you have started a program, the TNC displays the following
soft keys with which you can set the simulation speed:
Soft key Functions
Perform the test run at the same speed at
which the program will be run (programmed
feed rates are 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
