Restoration method 2): The travel value from the last synchronous control session is
[Main shaft]
Current value per
cycle after main =
shaft gear
[Auxiliary shaft]
Current value per
cycle after
=
auxiliary shaft
gear
The current value per cycle after main shaft gear/current value per cycle after auxiliary
shaft gear at the last synchronous control session is restored when "0: Invalid" is set in
"[Pr.400] Main input axis No."/"[Pr.418] Auxiliary shaft axis No.", or when a servo input axis
or a synchronous encoder axis as the main input axis/auxiliary shaft is not connected.
