4002 INTEGRATION TIME
Defines the PID Controller's integration
time.
Integration time is, by definition, is 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 adjustment procedure.
D (P 4001 = 10)
C (P 4001 = 1)
A = Error
B = Error value step
C = Controller output with Gain = 1
D = Controller output with Gain = 10
