time constant
(position
smoothing) Set the constant of a primary delay to the position command.
You can select a control method from "Primary delay" or "Linear
acceleration/deceleration" in [Pr. PB25 Function selection B-1]. When the linear
acceleration/deceleration is selected, the setting range is 0 ms to 10 ms. Setting of
longer than 10 ms will be recognized as 10 ms.
When the linear acceleration/deceleration is selected, do not set the "Control mode
selection" ([Pr. PA01]) to the setting other than "_ _ _ 0". Doing so will cause the
servo motor or linear servo motor to make a sudden stop at the time of position
control mode switching or restart.
(Example) When a command is given from a synchronizing encoder, synchronous
operation will start smoothly even if it start during line operation.
