6.2.4 S-curve filter for Position commands

The S-curve filter for Position commands smoothes the motion command in PR mode. The filter
makes the speed and acceleration continuous and reduces jerking, resulting in a smoother
6
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 (P1.036) and the acceleration / deceleration time in P5.020 - P5.035 can
increase the smoothness of operation. When the Position command source is the pulse input, the
speed and angular acceleration are continuous, so the S-curve command filter is not necessary.
