3.4 Buffer Memory Assignment
3.4.2 Details of the buffer memory
(28)CH Setting change rate limiter (Un\G52, Un\G84, Un\G116, Un\G148)
CH Setting change rate limiter (temperature rise) (Un\G52, Un\G84, Un\G116,
Un\G148)
CH Setting change rate limiter (temperature drop) (Un\G564, Un\G596,
Un\G628, Un\G660)
Set the change rate of the set value (SV) per a set time unit when the set value (SV) is changed. This setting can
regulate a rapid change of the manipulated value (MV). Set a time unit in CH Setting change rate limiter time
unit setting (Un\G735, Un\G751, Un\G767, Un\G783). ( Page 157, Section 3.4.2 (85))
(a) Batch/individual setting of temperature rise and temperature drop
Setting change rate limiter for the temperature rise and the temperature drop can be set in a batch or
individually. Select it on Switch Setting.
For details on the setting method, refer to the following.
Page 299, Section 6.2
When setting change rate limiter is set individually, Un\G52, Un\G84, Un\G116, Un\G148 is for the temperature
rise. The following table lists the buffer memory areas to be referred to.
For details on the function, refer to the following.
Page 190, Section 4.9
(b) Setting range
Set 0 or the value within the range 1 to 1000 (0.1% to 100.0%) toward the full scale of the set input range.
When 0 is set, the setting is disabled.
(c) Default value
The default values are set to 0 in all channels.
