Adjustment Level Section 5-4
• The MV Change Rate Limit parameter sets the maximum allowable varia-
tion in the MV per second. If the change in the MV exceeds this setting,
the MV will be changed by the MV change rate limit until the calculated
value is reached. If the limit is set to 0.0, this function will be disabled.
• The MV Change Rate Limit parameter will not operate in the following sit-
uations.
• In manual mode
• During ST execution (Cannot be set when ST is ON.)
• During AT execution
• During ON/OFF control
• While stopped (MV output during STOP)
• During MV output when error occurs

• This parameter sets the extraction of square root low-cut point used for
the inputs. The data after extracting the square root is shown below.
• The low-cut point is used for extracting the square root for flowrate sen-
sors.
