6.3.4 Offset Value
Pitch error offset amount of each axis is set according to the following table, and offset amount is
input in diameter value without relating to diameter programming or radius programming, and the
input value unit is the least input increment.

6.4 Notes of Offset Setting
The setting and alteration of pitch offset can only be done at the authority of password level 2.
①
②
After the parameter of pitch offset is set, only the machine zero is returned could the offset be
done.
6.5 Setting Examples of Offset Parameters
Assume that the pitch error compensation range is 0~255.
①
Data parameter No.098 (pitch error origin) =0, Data parameter No.099 (offset interval)=10.000
When the pitch error origin is set to 0:
The offset value for the 1
st
segment is set by the position No.001 in the offset table, the offset
value for the 2
nd
segment is set by the position No.002 in the offset table, and the offset value for the
Nth segment is set by the position No.000+N in the offset table.
The machine zero is regarded as the reference point of pitch error origin, it begins to compensate
