The settings can be viewed on the Settings page of the VMC display. The Page UP and Page DOWN keys
may then be used to locate the correct list of settings. To scroll through this list, use the cursor up and cursor
down keys. Refer to the VMC Operators Manual for instructions on how to modify these settings.
1.
POWER ON the VMC. Release the E-STOP button and press RESET.
2.
In MDI mode, command an M17, then an M14, to position the VMC table.
3.
Manually push the pallet adjacent to the receiver from the APC to the receiver. If necessary, use
the chain position adjustment tool to rotate the chain until the chain drive roller clears the drive leg.
NOTE
:
M14 will align the receiver with Pallet #1 (the pallet nearest the front of the VMC).
M15 will align the receiver with Pallet #2 (the pallet nearest the rear of the VMC).
4.
Push the pallet between the receiver and the APC a number of times. As the pallet goes over the
receiver rollers, note if the Y or Z axis is out of alignment.
If the alignment is slightly off in the Y-axis, handle jog the table in the Y-axis (in increments of
.001) until pallet loading and unloading is smooth. Record the final Y-axis position in settings 122
and 124. These two settings should be set to the same value initially, and may be adjusted
separately later if either loading or unloading is not smooth.
If alignment appears to be incorrect in the Z-axis (height), adjust it by turning the leveling
screws until pallet loading and unloading is smooth.
5.
Push the pallet back onto the APC. In MDI mode, command an M15 to move the pallet to load
position #2. Repeat Steps 3 and 4 above for pallet #2.
The APC height and the Y-axis alignment (settings 122,124,126,128) are now set.
6.
In MDI mode, command an M18 to clamp the pallet and close the automatic door.
NOTE:
The message “PEND MOVE (Y)” will appear and motion will stop during an
M18. press “Y” to continue motion.
7.
The X-axis alignment must now be checked. To do this, perform the following steps :
To stop a pallet change in order to adjust the settings, press FEED HOLD at any time. This will cause the
pallet change to stop after the present step is completed. Pressing CYCLE START will restart the program. If
E-STOP is pressed during a pallet change, the motors will stop instantly, and the machine will have to be
reset. If one of the chain location switches is not tripped at this time, the chain position will also have to be
reset using the chain position adjustment tool.
WARNING
If a pallet change sequence is stopped for any reason (e.g. E-
Stop, power outage, or low air supply), both the pallet and chain
locations must be checked before operating the VMC. See the
Power Outage / E-Stop Recovery section of this manual.
Under no circumstances attempt to operate the VMC until the
pallet drive arm is disengaged from the pallet drive pin on the
chain.
