3 Move the cursor to the compensation value to be set or changed using
page keys and cursor keys, or enter the compensation number for the
compensation value to be set or changed and press soft key
[NO.SRH].
4 To set a compensation value, enter a value and press soft key
[INPUT].
To change the compensation value, enter a value to add to the current
value (a negative value to reduce the current value) and press soft key
[+INPUT]. Or, enter a new value and press soft key [INPUT].
A decimal point can be used when entering a compensation value.
An external input/output device can be used to input or output a tool offset
value. See III–9. A tool length offset value can be set by measuring the
tool length as described in the next subsection.
There are tool offset memories A, B, and C, which are classified as
follows:
Tool offset memory A
D codes and H codes are treated the same. Tool geometry compensation
and tool wear compensation are treated the same.
Tool offset memory B
D codes and H codes are treated the same. Tool geometry compensation
and tool wear compensation are treated differently.
Tool offset memory C
D codes and H codes are treated differently. Tool geometry
compensation and tool wear compensation are treated differently.
The entry of compensation values may be disabled by setting bit 0 (WOF)
and bit 1 (GOF) of parameter 3290 (not applied to tool offset memory A).
And then, the input of tool compensation values from the MDI can be
inhibited for a specified range of offset numbers. The first offset number
for which the input of a value is inhibited is set in parameter No. 3294.
The number of offset numbers, starting from the specified first number,
for which the input of a value is inhibited is set in parameter No. 3295.
Consecutive input values are set as follows:
1) When values are input for offset numbers, starting from one for which
input is not inhibited to one for which input is inhibited, a warning is
issued and values are set only for those offset numbers for which input
is not inhibited.
2) When values are input for offset numbers, starting from one for which
input is inhibited to one for which input is not inhibited, a warning is
issued and no values are set.
