Pinc Machine error
offset increment
method
Specify whether the incremental volume
method or absolute volume method is to
be used to set machine error offset data.
0: Absolute volume
method
1: Incremental
volume method

# Item Details Setting range
4001 cmpax Basic axis Specify the basic axis address for
machine error compensation.
1) For pitch error compensation‚ set the
name of the axis to be compensated.
2) For relative position compensation‚
set the name of the axis to be the base
axis.
X, Y, Z, U, V, W, A,
B, or C axis address
4002 drcax Compensation
axis
Set the compensation axis address for
machine error compensation.
1) For pitch error compensation‚ set the
same axis name as "#4001 cmpax".
2) For relative position compensation‚
set the name of the axis to be actually
compensated.
X, Y, Z, U, V, W, A,
B, or C axis address
4003 rdvno Division point
number at
reference point
position
Set the compensation data No. corre-
sponding to the reference point position.
The reference point is actually the base‚
so there is no compensation No. Set the
number that is decremented by 1.
4101 to 5124
4004 mdvno Division point
number at the
most negative
side
Set the compensation data No. that is on
the farthest negative side.
4101 to 5124
4005 pdvno Division point
number at the
most positive side
Set the compensation data No. that is on
the farthest positive side.
4101 to 5124
4006 sc Compensation
scale factor
Set the compensation amount’s scale.
When the compensation scale is set to
“1”, the compensation amount unit will be
the same as the output unit.
Compensation amount unit
= unit of output × compensation scale
0 to 99
4007 spcdv Division interval Set the interval to divide the basic axis.
Each compensation data will be the
compensation amount for each of these
intervals.

Set the parameters
corresponding to the 1st axis’
parameters 4001 to 4007 for each
axis.
A maximum of 6 axes can be
controlled‚ but as the relative
position is compensated‚ settings
for 10 axes can be made.
