AUTO ON Coolant on/off mode is controlled by M codes. (M08-ON
M09-OFF)
MANUAL ON Coolant is supplied in any operation.
Auto and Manual modes cannot be on at the same time.
SPINDLE GEAR
This function allows the operator to place the spindle in neutral. This enables the chuck
to be rotated by hand. The control has to be in Manual mode. This function is only for
models with a spindle speed change mechanism where some kind of mechanical gear
shifting and a neutral is involved. The following keys are associated with this function.
NEUTRAL
When this key is pressed the spindle is placed in the neutral state. The
gear position data is saved and can be recalled even after the power has
been turned off and back on again.
ENGAGE
By pressing this key, the spindle gear range selected previously is auto-
matically selected. The selected range is displayed on the CRT at the
MACHINE STATUS display on the ACTUAL POSITION display screen.
The corresponding M code will be shown (M41 – M44).
The lamp at the upper left corner of the ENGAGE key will light up when
the gear position and confirmation limit switch match. If they do not
match, the light will flicker at intervals of 0.4 sec. This holds true when
operating in Auto or MDI modes.
For a machine with a mechanical gear change mechanism but no neutral
position, the ENGAGE key LED will flicker during gear change opera-
tion. The LED will flicker until the confirmation signal is read. The
Cadet (LNC-8) has this feature.
The spindle speed does not change when the gear range is changed only the torque is
increased or decreased.
LOAD This function is an option which is used to monitor the cutting
MONITOR load of the feed axes or the spindle.
TOOL This button is used to rotate the turret. Push it once and the
INDEX turret will index one position. Keep the button pressed, the turret will
rotate until the button is released.
For two-saddle or two-turret models, the turret to be index has to be
selected via the turret select keys (INDIVIDUAL MODE) on the machine
operation panel.
In most cases the X or Z axis have to be at the positive variable soft limit
before the turret will index. This can be checked by observing the LIMIT
status lamp on the NC operation panel. As a precaution, a visual inspec-
tion of the turret should be made before attempting to rotate the turret.
