5.6.14 Automatic positioning function to the home position
POINT
You cannot perform automatic positioning from outside the position d ata
setting range to the home position. In this case, make a home position return
again using a manual home position return.
If this function is used when returning to the home posit ion again after performing a manual home position
return after a power-on and deciding the home p osition, automatic positioning can be carried out to the hom e
position at high speed. In an absolute position detectio n system, manual home position return is not required
after power-on.
Please perform a manual home position retur n beforehand after a power-on.
Set the input signals and parameter as follows.
