PARAMETERS
3
Pr. 29 = 4 (S-pattern acceleration/deceleration C)
With the S-pattern acceleration/deceleration C switch signal (X20), an acceleration/deceleration curve S-pattern 1
or S-pattern 2 can be selected.
As the acceleration/deceleration time during acceleration/deceleration, set the percentage to the acceleration/
deceleration time T in Pr. 380 to Pr. 383.
Parameter setting (%) = Ts / T ×100%
Operation
During Acceleration During Deceleration
X20 Signal
OFF Pr. 380 "acceleration S pattern 1" Pr. 381 "deceleration S pattern 1"
ON Pr. 382 "acceleration S pattern 2" Pr. 383 "deceleration S pattern 2"
REMARKS
• At a start, the motor starts at Pr. 13 "starting speed" when the start signal turns on.
• If there is a difference between the speed command and speed at a start of deceleration due to torque limit operation etc.,
the speed command is matched with the speed to make deceleration.

CAUTION
Change the S pattern acceleration/

changed during acceleration or
