Manual Operation and Setup
The TNC 122 provides two methods for manually moving the ma-
chine axes:
•
Axis direction buttons
• Positioning with Manual Data Input (see Chapter 4)
Changing the feed rate F
Some machines are equipped with a potentiometer to enable you
to vary the feed rate.
Moving the machine axes with the axis direction buttons
In the MANUAL OPERATION mode you can move a machine axis
by pressing the appropriate axis direction button on the machine
control panel. As soon as you release the button the axis stops.
Continuing machine axis movement
With the user parameter MP7680 (see Chapter 8) you can set the
TNC for continuing machine axis movement. The machine then
continues to move the axis after you have released the axis direc-
tion button. To stop the machine axis you must press a button
again (see example 2 below).
Example: Moving the machine axis with the machine axis direction
button in the Z+ direction (retracting the tool)
