[Md.400] Current value after composite main shaft gear
The current value after combining the main input and the sub input values going into the composite main shaft gear is stored
as an accumulative value.
Units are in position units of the main input axis (Page 24 INPUT AXIS MODULE). The unit is pulse if the main input axis
is invalid.
The current value after composite main shaft gear will be changed when the following operations are executed in the main
input axis during synchronous control.

*1 When "2: Clear feed current value to zero" is set in "[Pr.21] Feed current value during speed control" only.
Change method 1): The new current value after composite main shaft gear is calculated based on the current value of the
main input axis.
Current value after composite main shaft gear = Main input direction of composite main shaft gear  Main input axis current
value
Change method 2): The movement amount of the main input axis from the last synchronous control session is reflected to the
current value after composite main shaft gear.
Current value after composite main shaft gear = Current value after composite main shaft gear  Movement amount of main
input axis from the last synchronous control session
