6.3.3 Smooth Speed command

S-curve filter
During the process of acceleration or deceleration, the S-curve filter uses the three-stage
acceleration curve and creates a smoother motion profile. It avoids jerk (rapid change of
acceleration), resonance, and noise caused by abrupt speed variation. You can use the
following parameters for adjustment.
◼ The S-curve acceleration constant (P1.034) adjusts the slope of the change in acceleration.
◼ The S-curve deceleration constant (P1.035) adjusts the slope of the change in deceleration.
◼ The S-curve acceleration / deceleration constant (P1.036) improves the stability of the
motor when it starts and stops.
