9.11 PI control parameters (Control panel: Menu PAR -> P15)
15.7 P GAIN
This parameter defines the gain of the PI controller. If the value of the param-
eter is set to 100%, a change of 10% in the error value causes the controller
output to change by 10%.
15.8 I-TIME
This parameter defines the integration time of the PI controller. If this param-
eter is set to 1,00 second, the controller output is changed by a value corre-
sponding to the output caused from the gain every second. (Gain*Error)/s.
15.5 FEEDBACK VALUE MINIMUM
15.6 FEEDBACK VALUE MAXIMUM
This parameter sets the minimum and maximum scaling points for feedback
value.
