5433 Magnification for second cyclical pitch error compensation for each axis
[Input type] Parameter input
[Data type] Integeraxis
[Valid data range] 0 - 100
Set a magnification for second cyclical pitch error compensation for
each axis.
When 1 is set as the magnification for second cyclical pitch error
compensation, the unit of compensation data is the same as the
detection unit.
Example
If the rotary table rotates by 20 degrees per rotation of the gear, the
parameters are as shown below.
Compensation
amount number
10 11 12 13 14 15
Compensation
amount
0+1+2-1-1-1
In this case, the settings of the parameters are as follows:
Data number
5430 5431 5432
Setting
10 15 4.0 (deg)
CAUTION
CAUTION
1 Using the appropriate parameters, set the number of the most distant
cyclic second pitch compensation point on the - side of each axis and
the number of the most distant cyclic second pitch compensation point
on the + side of each axis. If the settings of these two parameters are 0
or the same, cyclic second pitch error compensation is not applied.
2 The number of compensation points that can be used in pitch error
compensation and cyclic second pitch error compensation is 0 to 1279
for a system with ten or fewer axes and 0 to 3071 for a system with 11
or more axes. The number of compensation points that can be used in
pitch error compensation decreases by the number of compensation
points used in cyclic second pitch error compensation.
3 When interpolated pitch error compensation is used, the pitch error
compensation amount is output in interpolated form in each cyclic
second pitch error compensation interval.
4 Cyclic second pitch error compensation is superimposed even on
rotation axis pitch error compensation,
5 The sum of the compensation amounts per rotation must always be set
to 0.
6 Cyclic second pitch error compensation cannot be used for an axis for
which spindle positioning is performed.
7 Cyclic second pitch error compensation is enabled after a reference
position return.
