Acknowledging the power interruption and moving to
the reference points

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 TNC and machine: The TNC

starts the operating system. This process may take several

minutes. Then the TNC will display the "Power interrupted"

message in the screen header.

Press the CE key: The TNC compiles the PLC

program.

Switch on the machine 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

displayed sequence: For each external axis, press
the

START key. If you have absolute linear and

angle encoders on your machine there is no need

for a reference run

The TNC is now ready for operation in the

mode.
