AUTOMATIC OPERATION
Programmed operation of a CNC machine tool is referred to as automatic operation. This chapter explains the following types of automatic operation:
S MEMORY OPERATION
Operation by executing a program registered in CNC memory
S MDI OPERATION
Operation by executing a program entered from the MDI panel S DNC operation Operation while reading a program from external input/output device
S PROGRAM RESTART
Restarting a program for automatic operation from an intermediate point
S SCHEDULING FUNCTION
Scheduled operation by executing programs (files) registered in an external input/output device (Handy File, Floppy Cassette, or FA Card)
S SUBPROGRAM CALL FUNCTION
Function for calling and executing subprograms (files) registered in an external input/output device (Handy File, Floppy Cassette, or FA Card) during memory operation
S MANUAL HANDLE INTERRUPTION
Function for performing manual feed during movement executed by automatic operation
S MIRROR IMAGE
Function for enabling mirrorimage movement along an axis during automatic operation
S MANUAL INTERVENTION AND RETURN
Function restarting automatic operation by returning the tool the position where manual intervention was started during automatic operation.
S MEMORY CARDBASED DNC OPERATION
Automatic operation by a program written to a memory card

MEMORY OPERATION
Programs are registered in memory in advance. When one of these programs is selected and the cycle start switch on the machine operator's panel is pressed, automatic operation starts, and the cycle start LED goes on. When the feed hold switch on the machine operator's panel is pressed during automatic operation, automatic operation is stopped temporarily. When the cycle start switch is pressed again, automatic operation is restarted. When the
RESET
key on the MDI panel is pressed, automatic operation
terminates and the reset state is entered. For actual operation, refer to the manual supplied by the machine tool builder. Procedure for Memory Operation 1 Press the MEMORY mode selection switch. 21 Press
PROG
to display the program screen.
22 Press address O . 4 To stop or cancel memory operation midway through, follow the steps below. a.
Stopping memory operation
Press the feed hold switch on the machine operator's panel. The machine responds as follows: (i) When the machine was moving, feed operation decelerates and stops. (iii) When M, S, or T was being executed, the operation is stopped after M, S, or T is finished. When the cycle start switch on the machine operator's panel is pressed while the feed hold LED is on, machine operation restarts. b.
Terminating memory operation
Press the
RESET
key on the MDI panel.
Automatic operation is terminated and the reset state is entered.

When a reset is applied during movement, movement decelerates then stops.
Explanation
Memory operation After memory operation is started, the following are executed: (1) A oneblock command is read from the specified program. [. . . ] (3) Replace the fan or servo amplifier unit.
