4002 INTEGRATION
TIME
Defines the integration time for the process PID1 controller.
The integration time defines the rate at which the controller
output changes when the error value is constant. The
shorter the integration time, the faster the continuous error
value is corrected. Too short an integration time makes the
control unstable.
60.0 s
0.0 = NOT SEL
0.1…3600.0 s
Integration time. If parameter value is set to zero, integration
(I-part of the PID controller) is disabled.
1 = 0.1 s
