4. OPERATION
4.7.14 Automatic positioning function to the home position
POINT
You cannot perform automatic positioning from outside the position data
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 position again after performing a manual home position
return after a power-on and deciding the home position, automatic positioning can be carried out to the home
position at high speed. In an absolute position system, manual home position return is not required after
power-on.
Please perform a manual home position return beforehand after a power-on.
Set the input signals and parameter as follows.
