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%
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.

• Base frequency setting (acceleration/deceleration time setting) ⇒ Pr. 3 "base frequency" (Refer to page 77.)
• Pr. 20 "acceleration/deceleration reference speed" ⇒ Refer to page 78.
• X20 signal setting when Pr. 29 = 4 (S-pattern acceleration/deceleration switch) ⇒ Pr. 180 to Pr. 187 (input terminal function
selection) (Refer to page 150.)
• Starting speed setting ⇒ Pr. 13 "starting speed" (Refer to page 84.)

CAUTION
Change the S pattern acceleration/

becomes constant. S pattern operation
before switching continues even if the X20 is
changed during acceleration or
deceleration.
