・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.
Two-stage Acc/Decel change
Code/Name

Select method to switch to
Acc2/Decel2 profile, 1st-motor
AC116
Acc1 to Acc2 frequency
transition point, 1st-motor
AC117
Decel1 to Decel2 frequency
transition point, 1st-motor
・In the Acc2/Decel2 time, forward/reverse change can be
done when intelligent input terminal 031[2CH] is ON
and the set frequency in [AC116]/ [AC117] is reached.
・Sets Acc/Decel time 1[AC120][AC122] and Acc/Decel
time 2 [AC124] [AC126].

・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.
