This rotary switch is not effective in Auto mode with G00 programmed
and Single Block mode off.
PULSE The pulse handle is used to manually feed the individual axes.
HANDLE The control must be in Manual mode to use the pulse handle.
A magnification selection and an axis selection button determines which
axis movement is initiated. The magnification selection is used to select
the axis feed amount per pulse (notch).
1/1 Axis moves 1µm/pulse (.001 mm)(.0001in/pulse in inch mode).
10/1 Axis moves 10µm/pulse (.01 mm)(.001in/pulse in inch mode).
50/1 Axis moves 50µm/pulse (.05 mm)(.005in/pulse in inch mode).
SPINDLE These buttons are used to manually turn and stop the spindle.
STOP Stops the spindle rotation after the CCW or CW buttons have been
pressed.
CCW Makes the spindle turn counter clockwise. Must press the STOP button to
stop the rotation.
CW Makes the spindle turn clockwise. Must press the STOP button to stop
the rotation.
JOG With this button pressed, the spindle will rotate clockwise. Forward
rotation will stop as soon as the button is released.
For the CCW and CW buttons to work properly, the following conditions must
be met:
1. The spindle speed has been entered beforehand through MDI.
2. The spindle gear range selection (M41–M44) has been made.
3. For center work, the tailstock is advanced.
4. Chuck fulfills the spindle rotation condition:
Chuck closed during OD gripping.
Chuck open during ID gripping.
On machine models with DC spindle drive motors, it is not possible to go from CW to
CCW instantaneously.
SPINDLE OVERRIDE
The spindle override rotary switch is used to modify the commanded
spindle speed. This switch will not override the maximum allowable
spindle speed or the spindle speed set by the G50 code.
