Setting the speed of the test run
After you have started a program, the TNC displays the following soft
keys with which you can set the simulation speed.
You can also set the simulation speed before you start a program:
 Switch to the next soft-key row.
 Select the function for setting the simulation speed.
 Select the desired function via soft key, e.g.
incrementally increasing the test speed.
You can set the speed of the test run only if the “Display
of machining time” function is active (see “Activating the
stopwatch function” on page 581). The TNC otherwise
always performs the test run at the maximum possible
speed.
The most recently set speed remains active, even after a
restart, until you change it.
Functions Soft key
Execute test run at the same speed at which the
program will be executed (programmed feed rates are
taken into account).
Increase the test speed incrementally.
Decrease the test speed incrementally.
Test run at the maximum possible speed (default
setting).
