# Configuration requirements

This application assumes that the configured axes are created as axes with a separate interpolator (SAI). In this case it is sufficient to create the axes as spindles in the axis parameter

- lists: kenngr.achs_typ 4

or

- to activate the individual axis interpolator for other axis types by
  kenngr.configure_sai 1

All axes which are to be commanded by function blocks according to PLCopen specification Part 4 must be made known at the time of configuring the axis groups and must therefore be entered in the channel parameter lists.
