Code Description
4002 INTEGRATION TIME
Defines the integration time of the PID controller.
Integration time is, by definition, the time required to increase the output
by the error value:
• Error value is constant and 100%.
• Gain = 1.
• Integration time of 1 second denotes that a 100% change is achieved
in 1 second.
0.0 =
NOT SEL
0.1...600.0 = Integration time (seconds).
• See 4001 for the adjustment procedure.
