27 Setting the Machine Error Compensation
27.2.2.2 When the basic axis is a rotary axis
This section describes how to set bidirectional pitch error data by taking a rotary axis having a pitch error such as
illustrated below as an example.
Set the pitch error compensation data for an rotary axis in the same way as a linear axis.
However, note the following points.
- Set the interval between two division points so that the last division point will be 360 degrees.
- The sum of compensation amount being set in the incremental amount method will always be "0".
- The compensation amount of the last point in the absolute amount method (360 degrees) will always be "0".
