10.13 PID control parameters
(Control panel: Menu PAR
Feedback value minimum
Feedback value maximum
This parameter sets the minimum and maximum scaling points for feed-
back value.
Controller feedback [%]
Par. 14.6
Par. 14.5
0 V

Par. 6.2/6.6
0 mA
Fig. 66. Feedback minimum and maximum
P gain
This parameter defines the gain of the PID controller. If the value of the
parameter is set to 100%, a change of 10% in the error value causes the
controller output to change by 10%.

PID controller I-time
This parameter defines the integration time of the PID controller. If this
parameter is set to 1,00 second, the controller output is changed by a value
corresponding to the output caused from the gaine very second. (Gain × Er-
ror)/s.
PID controller D-time
This parameter defines the derivative time of the PID controller. If this pa-
rameter is set to 1,00 second, a change of 10% in the error value causes the
controller output to change by 10%.
