(Note-1): The output axis during synchronous control synchronizes with the input axis. Therefore, the output
axis depends on the input axis operation and synchronous control parameter, and the setting value
is invalid during the synchronous control.
However, at synchronous control stop during output axis operation, the setting value is valid since
the stop is processed after the synchronous control completion, and the output axis decelerates to
stop with the following slope of deceleration.
Slope of deceleration = Sped limit value
÷
Rapid stop deceleration time
(Note-2): The setting of S-curve ratio is invalid.
If a value other than 0% is set to the S-curve ratio, the stop processing is performed with
trapezoidal acceleration/deceleration (S-curve ratio = 0[%]).
(Note-3): When "1: Adv. S-curve" is selected, the setting is invalid, and the stop processing is performed with
trapezoidal acceleration/deceleration (S-curve ratio = 0[%]).
