Upper limit of closed loop output
(%)

P51.14 - P51.16 set the limit value in the process closed loop control. If it is above the input upper
limit P51.14, adjust it according to the upper limit; if it is lower than the lower limit, PID adjustment
will not be performed. This is how it sets the limit value in the process closed loop control.

When the closed loop process suddenly changes, these two parameters can be adjusted to control the
reference within a certain response time, so that the response of the closed loop process is stable in
some circumstances.

P51.24 - P51.27 defines the relationship curve between the analog closed loop reference and the
desired feedback. The set value is the percentage of the actual value of the set and feedback physical
quantities relative to the reference value (10V or 20mA).
