6.3 Incremental Jog Mode

6.3 Incremental Jog Mode
Incremental jogging can only be done upon power-on state of the machine, i.e. when there is
no
EMG (emergency stop) state in the rightmost field (general NC state) of status bar. After
selecting the operation mode in the 2
nd
field of status bar caption INCR appears.
If the machine is mounted with NCT machine control board the incremental jog mode can be
switched on by pressing the button.
Increment Selection
After selecting the operation
mode an increment size must be
selected. This can be done on the
OPERATOR’S PANEL or
POSITION screen. After
pressing the
F3
action menu key
INCREMENT, the desired
increment size can be selected
with the help of softkeys. The
selected increment size can be
seen in the 5th (interpolator)
field of status bar. The increment
size means the number of
increments the selected axis
moves by pressing the axis
direction button once.
If the machine is mounted with NCT machine control board the increment size can also be
selected directly by buttons , , , .
The increment size stepped by the control (1, 10, 100, 1000 increments) is always interpreted
in the output system of the machine (metric or inch). The output increment system is deter-
mined by the measuring system adapted to the machine. If, for example, in case of a machine of
metric system (the output increment system is metric), the resolution is 0.001mm, the control
is set to G20 (inch input programming) state and 1000 increment size is selected, on the
position display of distance to go 0.0394 will be displayed as distance, which is 1 mm
increment size in inch.
If data input and position display is done in diameter on axis X, the selected incremental step
will be done in diameter too.
Axis Selection
After setting the increment size by pressing axis jog buttons the step
is started on the selected axis and in the selected direction.
