Switch-on and crossing over the reference points can
vary depending on the machine tool. Refer to your
machine manual.
Switch on the power supply for control and machine. The TNC
starts the operating system. This process may take several
minutes. Then the TNC will display the message "Power
interrupted" in the screen header
Press the CE key: The TNC compiles the PLC
program
Switch on the control voltage: The TNC checks
operation of the emergency stop circuit and goes
into the reference run mode
Cross the reference points manually in the

machine START button. If you have absolute linear
and angle encoders on your machine there is no
need for a reference run
