Description
Proportional
band
Pb1
0…9999 Dimension of the proportional band
The larger the proportional band the
lower the controller amplification.
At Pb1,2=0, the controller structure
is ineffective (limit comparator
behavior). For the continuous
controller Pb1,2 must be >0.
Pb2
1)
0…9999
Derivative
time
dt
0…80…
9999s
Influences the differential component
of the controller output signal
The larger the derivative time the
higher the effectiveness of the D
component.
Reset time
rt
0…350…
9999s
Influences the integral component of
the controller output signal
The larger the reset time the lower
the effectiveness of the I component.
1) For 3-state controllers only (controller output 2)
