no flat part??

The previous line means a there is a flat part indeed, and I think it is
compatible with what the manual says

"...The
    maximum allowable following error will always be greater than
MIN_FERROR. This prevents
    small following errors for stationary axes from inadvertently
aborting motion. ..."

I assume that in case of parallel kinematiks' following error is
measured in joint coordinates...

Thanks very much
