7.5.9
High Output Clamping Limit (PRoG > PId > %HI)
Select the High Output Clamping Limit (
%HI
) parameter. This parameter sets the upper limit
for %power to analog outputs or %on time for PWM control with the other output types. (The
default setting is 100.0%.)
Set the desired value.
Confirm the value.
7.5.10
Adaptive Tuning (PRoG > PId > AdPt)
Select the Adaptive Tuning (
AdPt
) parameter.
Navigate to the desired setting. When adaptive tuning is enabled, the PID parameters are
continually optimized based on the process input changes caused by the current output
control parameters. This is the easiest way to optimize the PID algorithm for a wide variety of
systems. Adaptive tuning minimizes overshoot and decreases settling time. Autotune is
recommended for setting up adaptive tuning feature.
Settings include the following:
ENbL
–
Enables fuzzy logic adaptive tuning (factory default)
dSbL
–
Disables fuzzy logic adaptive tuning
Select the indicated setting.
7.6
PID.2 Configuration (PRoG > PId.2)
Note:
PID.2 is an independent control channel with separate configuration parameters. Both
PID and PID.2 channels drive toward the same Control Setpoint. PID.2 channel is useful when
the process is being controlled by two actuators with completely different characteristics. To
minimize interactions between the two loops, consider adding a process
7.7
Remote Setpoint Configuration (PRoG > RM.SP)
Select the Remote Setpoint Configuration (
RM.SP
) parameter.
Navigate to the desired setting. A remote signal can then be used to set and/or change the
Setpoint value using an analog input. This function can be used for a variety of applications
where direct access to the controller for Setpoint manipulation is a problem (hazardous
environments, lack of proximity, etc.). It can also be used to configure the controller in a
cascaded control scheme. Settings include the following:
oFF
–
Do not use a remote Setpoint (factory default)
oN
–
Remote Setpoint replaces Setpoint 1
Note:
oFF
has no sub-parameters, but
oN
requires scaling of the remote Setpoint input.
Select the indicated setting.
