14.1 Program Format Switch
Program format switch OFF
When the Program format switch request signal (PFCHR: YD00) is turned OFF, the control switches the program format from
M-system back to L-system G code system (a system selected by the parameter "#1037 cmdtyp"). When cancel of the
program format switch is completed, the Program format switch in progress signal (PFCHS: XCF0) turns OFF. If you start
automatic operation with the Program format switch in progress signal (PFCHS: XCF0) OFF, the control runs a program
based on the L-system G code system.

 If you change the Program format switch request signal (PFCHR: YD00) from ON to OFF during automatic operation (In
automatic operation signal "run" (OP: XC12) is ON), the operation error (M01 0215) occurs and the program format switch
is not implemented. Turning OFF of this signal cancels the operation error (M01 0215).
 If you turn OFF Program format switch request signal (PFCHR: YD00) and then start automatic operation in any G modal
state that disables program format switch, the program error (P29) occurs and automatic operation is not implemented.
 After turning OFF Program format switch request signal (PFCHR: YD00), wait until Program format switch in progress sig-
nal (PFCHS: XCF0) turns OFF before you execute automatic operation. Otherwise, it cannot be assured that "the control
runs a program based on the G code system at power ON from the top block of the program".
 When the parameter "#1319 Grp24_mdrst_off" is "0" and the modal retention reset is performed, the state of the program
format switch or the switch cancel is held even if the automatic operation is started with Program format switch request sig-
nal (PFCHR: YD00) OFF.
