Note: Notes on use of S-shaped acceleration/deceleration1. In case of frequency setting change in S-shaped
acceleration/deceleration, S-shaped acceleration/deceleration shall be restarted from its starting point under new frequency setting.
Therefore, the change in actual output frequency is not a smooth curve at the starting point of frequency change.
2. If F1002 is set to 2-20, and frequency is set through the external analog signal, the analog signal will constantly change due to
influence overlap of interference component and the ripple component etc.. Therefore, in this case, the possibility that the
change of actual output frequency can not form a smooth curve exists because of the reason described in
please increase the analog signal filter time constant of F1407 — F1409, and detect effective number of bits by further
adjusting the VIF of F1423 — F1425 to achieve stable analog signal.
3. In case of frequency locking (forward run signal and reverse run signal are input at the same time in operation of external
terminals), if acceleration / deceleration is interrupted at a time point, the output frequency value will remain fixed. At the
frequency unlocking time point, it will return to the original S-shaped acceleration/deceleration for the remaining frequency
change.
Example) If the frequency is locked at 20Hz during acceleration from 10Hz to 50Hz, stable operation will be kept at the
locked frequency 20Hz, and S-shaped acceleration will restart from 20Hz to 50Hz when the frequency is unlocked.
4. In the S-shaped acceleration/deceleration, the change of acceleration/deceleration time (F1011- F1019) becomes active from
the next acceleration/deceleration. Similarly, when switched to other acceleration/deceleration mode controlled by external
control terminals in acceleration/deceleration (2nd acceleration/deceleration, etc.), it also becomes active from the next
acceleration/deceleration
5. In case of current limiting function in S-shaped acceleration/deceleration, the remaining acceleration/deceleration is
temporarily changed to linear acceleration/deceleration to carry out acceleration/deceleration.
6. The acceleration/deceleration is carried out according to linear acceleration/deceleration curve when current limiting function
works in stable condition.
7. The acceleration/deceleration is also carried out according to S-shaped acceleration/deceleration curve in JOG operation.
