[Md.400] Current value after composite main shaft gear (R: D39120L+32n/Q:
D13600L+30n)
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. The unit is pulse if the main input axis is invalid. (Page 31 Servo input
axis position units, Page 39 Command generation axis position units, Page 55 Synchronous encoder axis position
units)
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.

current value update request command (R: M40172+32n/Q: M10972+20n)".
*2 When it starts by turning OFF the "[Rq.1152] Feed current value update command (R: M34492+32n/Q: M3212+20n)".
*3 When setting as a slave CPU synchronous encoder axis type (master CPU servo input axis, master CPU command generation axis,
master CPU synchronous encoder axis) in a Multiple CPU advanced synchronous control configuration.
■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 (Input +/Input -/No input
(0))×Main input axis current value
■Change method (2)
The travel value 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 at the last synchronous control
session+Main input direction of composite main shaft gear (Input +/Input -/No input (0))×Amount of change of travel value of
main input axis from the last synchronous control session
[Md.401] Current value per cycle after main shaft gear (R: D39122L+32n/Q:
D13602L+30n)
The input travel value after the main shaft gear is stored within the range from 0 to (Cam axis length per cycle - 1). The unit is
in cam axis cycle units. (Page 126 Cam axis cycle units)
The value is restored according to "[Pr.460] Setting method of current value per cycle after main shaft gear (R: D42740+160n/
Q: D15100+150n)" when starting synchronous control. (Page 145 Current value per cycle after main/auxiliary shaft gear
at synchronous control start)
