6.4 Notes of Offset Setting
①The setting and alteration of pitch offset can only be done at the authority of password
level 2.
②After 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.
①Data 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 1st segment is set by the position No.001 in the offset table, the
offset
value for the 2nd 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
the position No.001 in the offset table from the machine zero. So the pitch error offset can
only be
done in the positive moving direction of the machine coordinate system.

Ⅲ Connection
The position No.000 in the offset table corresponds to the reference point (i.e. pitch error
origin
0), the offset point 1 corresponds to a point of positive 10.000 moving from this reference
point, and
So there is a offset point every 10.000 mm. l. At offset point N, set an offset value which is
the
compensation amount by moving from (N-1)×(offset interval) to N×(offset interval).
The following table content is resulted from the above:
Actually the machine moves from the reference point to the point of +30.000, the pitch
error offset
is: (+7)+(-6)+(+4)=+5
②Data parameter No.098 (pitch error origin) =60, No.099(offset interval) =10.000
When the pitch error origin is set to 60:
For the positive moving, the 1st segment error offset is set by position No.061 in the offset
table,
the 2nd segment by position No.062. The Nth segment error offset is set by position
No.060+N in the
offset table.
