(a) The current value will be the same as the drive module current value of the
main shaft side at the virtual mode switching.
(b) When the current value change is executed toward the drive module current
value of the main shaft side, the current value after main shaft's differential
gear is also simultaneous changed to the specified current value.
(c) If the differential gear is not connected with the main shaft, drive module
current value of the main shaft side is always stored in the current value
storage register after main shaft’s differential gear.
(d) In the case of following figure, use "current value after synchronous encoder
axis main shaft's differential gear" of axis 1 as "current value after
synchronous encoder axis main shaft's differential gear".
(The drive module feed current value of the auxiliary input axis side is stored
as "current value after synchronous encoder axis main shaft's differential
gear" of axis 2.)
