Press the machine axis direction button as often as desired.
• Incremental jog positioning can vary depending on the individual machine tool. Your machine manual provides
more information on this function.
• The machine tool builder determines whether the interpolation factor for each axis is set at the keyboard or
with a step switch.
Positioning with manual data input (MDI)
Machine axis movement can also be programmed in the $MDI file (see page 5-45).
Since the programmed movements are stored in memory, you can recall
them and run them afterward as often as desired.
