1 CYCLE Pressing this key automatically carries out one complete
START automatic tool change cycle. This operation consist of a series of tool
change cycles in which a tool picked up from the magazine is set into the
spindle and the tool that was in the spindle is returned to the magazine.
This operation is only allowed when the message “READY” is displayed
on the CRT with the ATC sequence number set at “01”.
RETURN This button can be pressed with the ATC operation sequence set
CYCLE to any number. If the tool change arm has not completed its 180
START degree rotation, pressing this button will start the tool return cycle and no
tool change cycle will occur. If this button is pressed after the tool change
arm has completed its 180 degree rotation, the automatic tool change
cycle will be completed.
1 STEP Pressing this key advances the ATC operation one step at a time.
ADVANCE If the “RUN” message is being displayed on the CRT, this key will not
work. If the sequence does not advance because of some unfulfilled
condition, it is possible to ignore those conditions and continue opera-
tions. Pressing the 1 Step Advance key while holding down the INTER-
LOCK RELEASE key will allow the operation to continue. If a mechani-
cal condition is not met, the operation is not allowed to continue and the
“RUN” message is displayed on the CRT.
1 STEP The function of this key is the same as the 1 STEP ADVANCE
REVERSE key except the operation is done in reverse.
If the E-STOP button is pressed while the tool change arm is in operation, the signals AHP (X,Y,
and Z-axis tool change position) and SHP (spindle orientation complete) turn off. This some-
times renders the ATC operation keys inoperative. If so, press the 1 STEP ADVANCE key while
pressing the INTERLOCK RELEASE key, and the tool change sequence will advance to the next
step.
The tool in the spindle will be clamped when the ATC cycle is interrupted by an E-STOP condi-
tion. This will render the ATC operation keys inoperative. In this case, press the TOOL
UNCLAMP button on the operation panel at the side of the main operation panel.
APC Operation
The control must be in MANUAL mode and the APC key on for the following keys to be
effective.
1 CYCLE When this key is pressed, one automatic pallet change cycle is
START carried out. During this operation, the pallet on the machine is unloaded
to the APC and the pallet on the APC is loaded to the machine. This
operation is effective only if the “READY” message is displayed on the
CRT.
RETURN When this key is pressed, the automatic pallet change cycle is
CYCLE carried out in the reverse order back to sequence number “01”.
START This will return the pallet to the machine.
1 STEP The automatic pallet change cycle will advance step by step every
ADVANCE time this key is pressed. This operation is ineffective if the “RUN” mes-
sage is displayed on the CRT.
