S-curve filter (Position)

The S-curve filter smoothes the motion command in PR mode. This filter makes speed and
acceleration continuous and reduces jerking, resulting in a smoother mechanical operation. If the
load inertia increases, the motor operation is influenced by friction and inertia when the motor
starts or stops rotating. Setting a larger acceleration / deceleration constant for the S-curve (TSL)
and for the acceleration / deceleration time in P5.020 – P5.035 can increase the smoothness of
operation. When the Position command source is pulse, the speed and angular acceleration are
continuous, and the S-curve filter is not necessary.
