1 sec 60 sec 3 sec
Cycle time also known as duty cycle, the total length of time for
the controller to complete one ON/OFF cycle.
Example :
With a 20 second cycle time, an on time of 10
seconds and an OFF time of 10 seconds represents a 50
percent power output. The controller will cycle ON and OFF
while within the proportional band.

Term P is proportional to the current value of the SV-PV error .
Example :
If the (SV-PV) error is large and positive, the control
output will be proportionately large and positive and vice versa if
error is negative.
Function: Sets proportional band.

Term I accounts for past values of the SV-PV error and
integrates them over time to produce the I term.
Setting "0" will turn OFF integration.
Example :
If there is a residual SV-PV error after the
application of proportional control, the integral term seeks to
eliminate the residual error by adding a control effect due to
the historic cumulative value of the error.

Function: Sets differential time.
21
Parameter
Sets the differential time of PID parameter.
Setting "0" will turn OFF differential.
Term D is a best estimate of the future trend of the SV-PV error,
based on its current rate of change. It is sometimes called
"anticipatory control", as it is effectively seeking to reduce the
effect of the SV-PV error by exerting a control influence
generated by the rate of error change. The more rapid the
change, the greater the controlling or dampening effect.
