5.2.3 Position smoothing
By setting the position command acceleration/deceleration time constant (parameter No.PB03), you can run
the servo motor smoothly in response to a sudden position command.
The following diagrams show the operation patterns of the servo motor in response to a position command
when you have set the position command acceleration/deceleration time constant.
Choose the primary delay or linear acceleration/deceleration in parameter No.PB25 according to the machine
used.

(2) For trapezoidal input
For trapezoidal input (linear acceleration/deceleration), the setting range is 0 to 10ms.
