Yaskawa Motoman RCS not initializing

Yaskawa Motoman RCS not initializing

When working with Yaskawa robots there is a mandatory step to create the .ctl file. To create the .ctl file,

go into Robot > Setup > Robot Properties > External Axes Setup at least once, so that the .ctl is created under the machine data files folder.

Not sure why the RCS needs this file when there are no external axes, but that's the way the Yaskawa RCS works.
