Acceleration S-Curve
Settings 00 to 07 Factory Setting: 00
This parameter is used whenever the motor load needs to be accelerated or decelerated
smoothly. The desired accel/decel effect is selectable from 0 to 7, in which the larger the
number, the greater the effect achieved. If the default value of Pr.111 Deceleration S Curve is
unchanged (“0”), then Pr.14 sets both acceleration and deceleration S-Curves. If Pr.111 is set
to any value other than “0”, then Pr.14 will set the acceleration S-Curve and Pr.111 will set the
deceleration S-Curve.
