Coincidence Detection
Function Use Selection
Set whether or not the coincidence detection *2 is to be used. 1 word Not use
06
Coincidence Interrupt
Function Use Selection
Set whether or not the coincidence interrupt function *2 is to
be used.
(Valid only when the coincidence detection function is set.) 1 word Not use
07 Axis Selection Set the axis type *3 : Finite or infinite length axis. 1 word Finite length axis
08 Reference Unit Selection
Specify the reference unit.
