Operation
ber is entered by keying the number and then pressing the Write/Enter key.
For example, keying “O123”, then Write/Enter will put the program number
O00123 into the table.
If a parts program encounters an M50 (without a P code) and the Part Ready
button has not been pressed, the control will pause operation, the beacon will
blink green, and the message “None Scheduled” is displayed. The mill will wait
until the Part Ready button has been pressed, or the PST has been updated,
before performing the pallet change. This feature prevents a pallet change from
occurring before the operator is ready. The Part Ready button can be pressed
at any time and will be recognized when the next pallet change is required.
Method 2
Although the previous method is recommended, the pallet changer can also be
operated without automatic sequencing or PST inputs. This is done using M50
with a P code. For proper operation M50 must be preceded by M36. M36 P1
before the M50 P1 will check that pallet #1 is ready.
Pallets can be changed without automatic sequencing or PST inputs. This is
done using M50 with a P code. M50 P1 will load pallet #1 without checking
to see if it is scheduled. If the PART READY button has been pressed, then
pallet #1 will be loaded. If the PART READY button for pallet #1 has not been
pressed, the indicator light on the button will flash and the message, “Schedule
Pal#1” is displayed.
Pallet Schedule Table
The pallet schedule table incorporates a number of features to help the user
with their routine.
Load Order and Pallet Status
These two features work together to show
which pallet is currently in the machining area.
Pallet Usage
This feature gives the number of times the specific pallet has
been loaded into the machining area. The counter will turn over to 0 after
32767 pallet changes.
Program Number
This detail shows which program number has been as
-
signed to the pallet.
Program Comment
This area displays the comments that are written in the
part program.
There are 30 different pallet status values to use. The first four: Unscheduled,
Scheduled, Loaded, and Completed, are fixed and cannot be changed. The
remaining 26 can be modified and used as needed.
Changing or adding status text can be done in the PST. Use the arrow keys to
move the cursor to the “Pallet Status” column, and press the F1 key. A selec
-
tion menu will appear over the “Pallet Status” column (Pressing F1 again or
Reset will close the menu.) The number to the left of the text is the status num
-
ber. This number is used with the M49 command to set the status from the part
