(3) Supplementary Explanation

When the following conditions occur, the control unconditionally transfers the current values of
the absolute coordinate system (the CRT current value display second screen or the coordinate

system determined by the coordinate system setup command) to the command value register.

(a) Reset procedure: Turning ON the

panel reset key or closing the external reset

input.

(b) End-of-program: Resetting the program by executing the

command to close the

end-of-program

input.

After the absolute coordinate system current values are transferred to the command value
register, manual axis movement is reflected in automatic axis movement even if the

ABS in-

put is open.
If the reset procedure is performed after manual axis movement and the system searches

for block (1) and continues with it, the following motion path prevails.

RESTART INPUT (PRST # 30063) AND PROGRAM RERUN STATE

# 35044)

These signals are used to resume machining operations in the middle of a part program.
Close the SRN input, set up the memory mode, and search for the restart sequence number
from the NC operation panel.

The CRT display then shows the M, S, and T codes between the beginning of the program and
the retrieved sequence number.

While the program restart input is effective for the NC equipment, the program rerun state out-

put is closed.

NOTE

For the details of the program restart function, refer to the

i80L Instruction Manual.
