Set the secondary control operating amount change limiter ascent.
A limit is set to the ascent percentage of the operating amount change calculated.
An operating amount allowed with ascent for a second is set in the unit of percentage.

MLL 2 is set for the initial MV at power-on.
Note
(1) The setting is effective also during AT.
(2) When the setting is changed, re-AT is required due to different control result.
(3) The setting value of 100 % allows ascent of only 20 % in the input sampling (200 ms).
In order to have ascent of 100 % in the input sampling (200 ms), set the setting value to 500 %.
(1 s ÷ 200 ms) × 100 % = 500 %
Set the setting value to 0.0 % (OFF) when ascent of 110 % from 0 % in a second is desired for an analog input.
