d. A manual intervention was performed during
the axis shift to the return position.
(8) In type P, any of the following operations
performed in the time between the discontinuation
of machining and the search operation for pro-
gram restart will cause an error:
a. The setting of coordinate system was
fied.
ERROR . PRTN ERROR
b. The setting of work coordinate system was
specified.
ERROR 122 PRTN ERROR (G54 - G59)
c. The coordinate system was modified by
operation ORG key.
ERROR . . . PRTN E R R O R
In type P , the correct program restart is made
possible only for the blocks that follow the one
for which the coordinate-system setting was per-
formed last before the discontinuation of machin-
ing.
(9) If a specified block has not been found, it
will cause an error.
Error 120 PRTN ERROR (NOT FOUND)
( 10) After turning power on, operation for pro-
gram restart without any returning to reference
point will cause an error.
Error — ZR UNREADY
( 11) After search operation for program restart is
completed, if shaft is transferred by MDI before
moving shaft, it will cause an error.
Error 124 PRTN ERROR
( 12) In program restart operation during modifying
tool dia, MDI cannot instruct T or B . In this
case, use manual MD I operation (interruption into
actual buffer during modifying codes) .
(13 ) “PRN” blinks at the last line of CRT screen between
the times when program restart search is instructed
and when last Z-axis is completed to return.
( 14) In DNC operation or tape operation program
can not be restarted.
5.2.5.1 PLAYBACK t
The current axis position during movement can
be stored as command value in the part program.
This function is permitted in the PLAYBACK
mode when PLAYBACK switch is turned on in
manual operation mode.
To turn on PLAYBACK mode, activate the PLAYBACK
switch on the machine control station or set #6000
to “1”. Procedure for storing program in
the PLAYBACK
mode is as follows.
(1) Set the control in the manual operation mode
(RAPID , JOG, STEP, or HANDLE).
(2) Turn on the PLAYBACK switch.
(3) Depress the PROG key of function keys.
The CRT screen shows the contents of part pro-
gram number O plus 4 digits and the current
value at the bottom.
(4) Register the new program number after address O.
To register 01234, for example, key-in O, 1, 2, 3, 4 and
depress the key.
The numbers are displayed as they are keyed-in.

(5) Move the axis to the position which will be
written as command.
(6) Depress the address key for the axis whose
position is written.
(7) Depress the WR key.
The displayed current value is the command
value of the selected address. Key-in the
numerical data before depressing the WR key,
and the
amount of keyed-in value plus cur-
rent value will the new command value.
