(2) Cutter compensation C
When the offset numbers for cutter compensation C are specified or
modified, the offset number validation order varies, depending on the
condition, as described below.

(1)Offset number H01 is valid.
(2)Offset number H02 is valid.
(3)Offset number H03 is valid only for
the axis to which compensation
was applied most recently.

(1) Offset number H00 is valid.
(2) Offset number H02 is valid.
(3) Offset number H02 is valid.
(However, the H number displayed
is changed to 03.)
The tool length offset value may be set in the offset memory through the
CRT/MDI panel.
The range of values that can be set as the tool length offset value is as
follows.
Metric input Inch input
Tool length offset value 0 to ±999.999mm 0 to ±99.9999inch
WARNING
When the tool length offset value is changed due to a
change of the offset number, the offset value changes to the
new tool length offset value, the new tool length offset value
is not added to the old tool length offset value.
H1 : tool length offset value 20.0
H2 : tool length offset value 30.0
G90 G43 Z100.0 H1 ; Z will move to 120.0
G90 G43 Z100.0 H2 ; Z will move to 130.0
CAUTION
When the tool length offset is used and set a parameter
OFH (No. 5001#2) to 0, specify the tool length offset with H
code and the cutter compensation with D code.
D When OFH (bit 2 of
parameter No. 5001) = 0
D When OFH (bit 2 of
parameter No. 5001) = 1
