Operation
using PST.
Messages aid the operator with loading/unloading and pallet changes. For
example, at the beginning of the M50 pallet change, if the load station is not
ready, a message is displayed on the screen. The message will not stop flash -
ing and the pallet change will not continue until the load station is ready and
the Part Ready button is pressed. At the beginning of a pallet change, if the
load station is ready, no messages appears, and no button press is required,
and the pallet change starts directly.
M46 – Qn Pmm
Jump to line mm in the current program if pallet n is loaded, otherwise go to the
next block.
M48 – Validate that current program is appropriate for loaded pallet
Checks in the Pallet Schedule Table that the current program is assigned to the
loaded pallet. If the current program is not in the list or the loaded pallet is in-
correct for the program, an alarm is generated. M48 can be in a program listed
in the PST, but never in a subroutine of the PST program. An alarm will occur if
M48 is incorrectly nested.
M49Pnn Qmm – Sets the status of pallet nn to a value of mm.
Without a P-code, this command sets the status of the currently loaded pallet.
The status of each pallet are defined in the pull-down menu of the (PST).
Operator Load Station (EC-300, EC-400, MDC)
To ease loading/unloading parts and to speed production pallet changing mills
have an additional load area. The load station is guarded by a door, and a sub-
panel includes a few buttons to control the pallet changer. As a safety precau-
tion the load station door must be closed before a pallet change can occur.
NOTE: The load station pallet must be at home to do a pallet change.
