(Note-2): When it starts by turning OFF the feed current value update command (M3212+20n).
(a) Restoration 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
(b) Restoration 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 main
input axis current value
from the last synchronous
control session
The current value after composite main shaft gear at the last synchronous
control session is restored when "0: Invalid" is set in [Pr.400] Main input axis
No. (150n), or when a servo input axis or a synchronous encoder
axis as the main input axis is not connected.
