(c) S-type interpolation: The output is changed up to objective value with S-type during the interpolation time.

(3) Interpolation time setting
The interpolation time can be set with the one among 10[ms], 100[ms], 1[s], 60[s].
The output is changed depending on interpolation method setting during the set interpolation time.
(4) Interpolation output value
The interpolation operation value that is currently being outputted can check in parameter area while using
interpolation function.
(5) Interpolation flag turns on while the interpolation is outputted. And when the interpolation output value is reached at
objective value, it will turn off.
※ Interpolation flag can be monitored when interpolation time is set to 1[s] or 60[s].
