16.17 Machine Error Compensation Parameters

(PR) #4000 Pinc
Select the method to set the machine error compensation data.
0: Absolute amount method
1: Incremental amount method
#4001 cmpax
Set a name of the basic axis 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 basic axis.
Set "system No. + axis name" when using the multi-part system.
(Example) Z axis for 2nd part system: 2Z
When two or more same name exist, set "axis name + serial number".
The serial number is common to all systems.
(Example) If C axis of the 1st system has 2 axes, and another C axis in the 2nd system has 1 axis, set the C
axis of the 2nd system as "C3".
---Setting range---
Abbreviation as X, Y, Z, U, V, W, A, B, C, etc.
#4002 drcax
Set a name of the compensation axis for machine error compensation.
(1) For pitch error compensation, set the same axis name as in "#4001 cmpax".
(2) For relative position compensation, set the name of the axis to be actually compensated.
Set "system No. + axis name" when using the multi-part system.
(Example) Z axis for 2nd part system: 2Z
When two or more same name exist, set "axis name + serial number".
The serial number is common to all systems.
(Example) If C axis of the 1st system has 2 axes, and another C axis in the 2nd system has 1 axis, set the C
axis of the 2nd system as "C3".
---Setting range---
Abbreviation as X, Y, Z, U, V, W, A, B, C, etc.
#4003 rdvno
Set the compensation data No. corresponding to the reference position. As the reference position is actually
the base position, there is no compensation No. Therefore set the number that is decremented by 1.
(Note) When two-way pitch error compensation is enabled, set compensation data No. corresponding to ref-
erence point in shifting in plus direction.
---Setting range---
4101 to 5124
#4004 mdvno
Set the compensation data No. at the farthest end on the negative side.
(Note) When the axis moves in positive direction with two-way pitch error compensation enabled, set com-
pensation data No. of which locates on the nearest point to negative side. The compensation point should
be set with even number.
---Setting range---
4101 to 5124
