Parameter Description
Upper range Upper current value
value current that is mapped to the
upper nominal range
boundary selected by
Frequency value high
(9235). Applicable if
Process value (9204) =
25 or 26.
Lower range Lower current value
value current that is mapped to the
lower nominal range
boundary selected by
Frequency value low
(9237). Applicable if
Process value (9204) =
25 or 26.
Damping value Time constant of damp‐
ing filter for frequency
output signal.
Fail-safe activa‐ Fail-safe activation con‐
tion condition dition.
Fail-safe min. Minimum time the out‐
time put stays in fail-safe be‐
havior.
Fail-safe behav‐ Frequency output reac‐
ior tion in case of a fault.
Fail-safe value Output value in case of
a fault and when Fail-
safe behavior (9239) is
