・
When [AC-03]/[AC-04]=00(Linear), decelerates at
regular intervals towards the target value.
・
When [AC-03]/[AC-04]=01(S-curve), for a shockless
operation proceeds gradually at the beginning and at
the end of the acceleration and deceleration.
・
When [AC-03]/[AC-04]=02(U-curve), proceeds gradually
at the start of the acceleration and deceleration.
・
When [AC-03]/[AC-04]=03(Inverted-U-curve), proceeds
gradually at the end of the acceleration and
deceleration.
・
For S-curve, U-curve and Inverted-U-curve, the degree
in which the operation accelerates and decelerates can
be set with [AC-05]/[AC-06].
・
When AC-03]/[AC-04]=04 (EL-S-curve), proceeds
gradually at the beginning and the end of the
acceleration and deceleration.
・
For EL-S-curve shockless operation, the beginning and
the end of the acceleration and deceleration [AC-08]

[AC-11] should be adjusted.

Assign the Acc/Decel time that takes from 0Hz to reach
the maximum frequency.
・
In case that the two-stage Acc/Decel function is not
meant to be used, the Acceleration time 1 [AC120] and
Deceleration time 1 [AC122] are used.
・
Example of using the two-stage Acc/Decel function.
With[AC115]=00
*) Acc/Decel time is what takes from 0Hz to reach the
