D Actual Spindle Speed - If you have the rigid tapping option, you can verify the exact spindle speed by
checking on the right side of the first page on the CURNT COMDS display, where the actual spindle speed is
listed next to ACT Snnnn, and in the bottom right corner
.
D Optional Stop - Takes effect on the line after the highlighted line when pressed.
D A Block Delete - Takes effect four lines after that key is pressed when cutter compensation is in use, or two
lines later when cutter compensation is not in use.
D Block Look-Ahead - This control actually does look ahead for block interpretation, up to 20 blocks. This is
not needed for high-speed operation. It is instead used to ensure that DNC program input is never starved, and
to allow Cutter Compensation to have non-XY moves inserted while Cutter Compensation is On.
D Memory Lock Key Switch - This is a customer machine option that prevents the operator from editing or
deleting programs, and from altering settings when in the locked position. Since the Key switch (if installed)
locks out the Settings, it also allows you to lock out other areas within the settings: Setting 7 locks out
parameters: Parameter 57, 209, and 278 lock other features. Setting 8 locks all programs. Setting 23 locks
09xxx programs. Setting 119 locks offsets. Setting 120 locks macro variables. In order to edit or change these
areas, the key switch (if installed) must be unlocked and the setting turned off .
(Any Mill Control ver. 9.25 and above; any Lathe Control ver. 2.23 and above.)
D Chip Conveyor - The chip conveyor can be turned on or off when a program is running, either manually
using the control keys or in the program using M codes. The M code equivalent to CHIP FWD is M31, CHIP
REV is M32, and CHIP STOP is M33. You can set the Conveyor Cycle time (in minutes) with Setting 114, and
the Conveyor On-Time (in minutes) with Setting 115.
D Tool Offset Measure and Part Zero Set Measurement keys - With the touch of a key to enter in either a
tool length offset or a work offset to help save time during a part setup. The NEXT TOOL key is then used to
send the machine home for a toolchange to the next tool. The cursor will then position to the next offset
register and the increment for the handle will go back to 10. inches per minute.
D Transferring an MDI Program - You can transfer and save a program in MDI to your list of programs. When
in the MDI display, make sure that the cursor is at the beginning of the MDI program. Enter a program number
(Onnnnn) that’s not being used. Then press ALTER and this will transfer the MDI data into your list of programs
under that program number.
D To Rapid an Axis Home - You can rapid all axes to machine zero by pressing the HOME G28 key. You can
also send just one axis (X, Y, Z, A or B) to machine zero in rapid motion. Enter the letter X, Y, Z, A or B, then
press HOME G28 and that axis alone will rapid home. CAUTION ! There is no warning to alert you of any possible
collision! For example, if the Z axis is down near the part or fixture on the table, and then the X or Y axis is sent
home using HOME G28, a crash may result. Care must be exercised.
(Any Mill Control ver. 9.49 and above; any Lathe Control ver. 2.24 and above.)
D Rotating Tool Carousel without Changing Tools (M39) - You can rotate the tool carousel without chang-
ing tools by using M39 and Tnn. This can be used to recover from some unusual conditions. However, it will
also tell the control you have a different tool in the spindle, which may not be the case. You can disable this
command, if you choose, by turning on Setting 86, M39 LOCKOUT.
(Any Mill Control ver. 2.3 and above.)
