Operation selection functions 1 (Pr. 17 to Pr. 37)
Pr. 29 = 4 (S-pattern acceleration/deceleration C)
The S-pattern acceleration/deceleration C switch signal (X20) changes an acceleration/deceleration curve.

X20 Signal
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%
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 restriction operation
etc., the speed command is matched with the speed to make deceleration.
