1.3 ERROR COMPENSATION
1.3.1 Stored Pitch Error Compensation
Overview
If pitch error compensation data is specified, pitch errors of each axis
can be compensated in detection unit per axis.
Pitch error compensation data is set for each compensation position at
the intervals specified for each axis. The origin of compensation is the
reference position to which the tool is returned.
Pitch error compensation data can be set with external devices such as
the Handy File. Compensation data can also be set directly with the
MDI panel.
To specify the correspondence between compensation positions and
machine coordinates, the five parameters below must be set.
In the following example, 33 is set for the pitch error compensation
number at the reference position.
- Number of the pitch error compensation position at the reference
position (for each axis) Parameter (No.5420)
- Number of the pitch error compensation position having the
smallest value (for each axis) Parameter (No.5421)
- Number of the pitch error compensation position having the
largest value (for each axis) Parameter (No.5422)
- Pitch error compensation magnification (for each axis)
Parameter (No.5423)
- Interval of the pitch error compensation positions (for each axis)
