REMARK
"The last synchronous control session" indicates status just before the last
synchronous control session was stopped as follows. These are listed with the last
synchronization status.
• Just before [Rq.380] Synchronous control start (n) turns from ON to OFF.
• Just before deceleration stop by a stop command or an error, etc.
• Just before the Multiple CPU system power supply turned OFF.
(2) Current value per cycle after main shaft gear, current value per
cycle after auxiliary shaft gear when starting synchronous control
The current value per cycle after main shaft gear/current value per cycle after
auxiliary shaft gear is restored as follows according to the main input
axis/auxiliary shaft operation executed before starting synchronous control.

(Note-1): When it starts by turning OFF the feed current value update command (M3212+20n) or [Rq.347]
Feed current value update request command (20n).
(Note-2): When it starts by turning OFF the feed current value update command (M3212+20n).
(a) Restoration method 1)
The new value of the current value per cycle after main shaft gear/current
value per cycle after auxiliary shaft gear is calculated based on the current
value after composite main shaft gear/auxiliary shaft current value.
[Main shaft]
Current value per cycle
after main shaft gear
= Main shaft gear ratio
Current value after
composite main shaft gear
[Auxiliary shaft]
Current value per cycle
after auxiliary shaft gear
=
Auxiliary shaft gear
ratio
Auxiliary shaft current value
