(1) When ABS Input Relay is Open
The motion path after an intervention by manual axial motion, is
the one shifted parallel from the original path by the distance
cov-ered by the manual motion.

(3) Supplementary Description
In the following cases, the control transfers current value in the
absolute coordinate system (coordinate system displayed in the
CRT current value 2nd area, or the one determined by
coordinate system setting instructions) to the command value
register unconditionally.
. RESET operation: MDI panel RESET key-on or external reset
(ERS) input contact closed
. End of program: Program reset through end of program (EOP)
input contact closing by M02, M30 execution
. Automatic return to reference poin~ Execution of G28 command
After transfeming the current value in the absolute coordinate
system to the command value register, manual axial movement
even when the ABS input contact is closed.
When the block @ is searched again by the RESET operation
after axial motions by manual operation, the following motion
takes place.

19.2.11 SINGLE BLOCK (SBK) INPUT
This input is for executing part programs one block at a time in the
automatic operation mode. With the control in the automatic oper-
ation mode, and the SBK input contact closed, when an automatic
operation cycle is started, only one block of the part program is ex-
ecuted, and the machine stops. When the SBK input contact is
closed during the execution of a part program, the control stops the
machine after the execution of the current block.
For details of the use of single block during the execution of mul-
tiple cycles, user-macro programs, refer to "YASNAC J50L
Instruction Manual (TOE-C843-12.20)."
