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 trajectory. 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
status of motor activating and stopping. The servo drive can also calculate the total time for
executing the command. T (ms) indicates the operation time and S (rpm) indicates the absolute
Speed command, which is the absolute value of the initial speed minus the end speed.
