Writing of tool offset amount
The writing of the offset amount and other
offset memory contents is performed by the
following operations:
Depress the OFS function key,
By the operation of PAGE key and CURSOR
key or keying in two digits designate the
tooloffset number to be written.
Using the address key and the data key,
key in the address data to be written. In
this case, the meaning depends on the ad-
dress as shown below:
Address

Notes :
1.
The contents of offset memory are retained
after the power is turned off.
2.
Regardless of modes, the writing by the
above operations is always possible including
automatic run time.
3. The
tooloffset amount rewritten in automatic
run is made valid from reading of the com -
mand of the next block. For the tooloffset
amount of the currently executed block or
the block stored in the prefetch buffer, the
value before change is used.
4.
When the data shown below is rewritten, the
timing in which the data value is made
is as
follows:
Table 4.1
(i) Work coordinate s~stem shift amount:
Writing of an absolute value.
Namely, the value is written to
memory without change.
Writing of an increment. Namely,
the current value is added to the
5%
preceding value and the result is
written to memory.
Writing of an absolute value.
The time when G56, G50T , or other
coordinate system setting is performed
next.
ii) Tool coordinate data:
The time when G 50T is specified next.
iii) Tool wear compensation amount:
The tl,newhen T 99A A is specified next.
The writing operation of the above tool coor-
dinate data is performed when the PST INPUT
button is not depressed. If this button is
depressed, the data to be written is com-
pletely different from the above data. For
details,see 6.2.3 Work Measuring Value
Direct Input.
The contents of offset memory are allerased
by the following operations:

memory are all erased,
through d. to write allnecessary tooloffset
amounts.
f. When the options shown below are selected,
if the corresponding offset memory number
is designated at the operation of d. , the
data may be written to memory. However,
address R has no significance and therefore
should not be designated.
