Setting the speed of the test run
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 591). 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.
After you have started a program, the TNC displays the following soft
keys with which you can set the simulation speed.
Function
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).
