Leadscrew error compensation(kw.ssfk.*)

Leadscrew error compensation (referred to below as SSFK) is an axial correction. The position setpoint of the compensated axis is changed by a compensation value on the basis of position controller timing, in order, for instance, to compensate for leadscrew errors. This correction is cancelled by computation again for the measured actual position values so that the correction performed does not appear in the display data of the control system.

The SSFK data are stored in the corresponding compensation value list for each axis.

The general data of the list body are entered into the structure kw.ssfk.*. It contains following elements.
