receive on the 1-bit communication object "Enable". The function is block if an OFF
telegram is receive on the 1-bit communication object "Enable". This means that no
telegram is sent out on the "Output" communication object.
12.27.4
Extended parameter – Group object value
Options
Normal
Inverse
Note: This object is only adjustable if the "Enable object" parameter is set to
"activated".
The enable function normally functions as follows:
The function is active if an ON telegram is receive on the 1-bit communication object
"Enable". The function is block if an OFF telegram is received on the 1-bit communication
object "Enable".
Via the parameter "Logic of the enable function", the above-described behavior can be
reversed, i.e. if an ON telegram is received on the 1-bit communication object "Enable",
the function is blocked. The function is active if an OFF telegram is received on the 1-bit
communication object "Enable".
12.27.5
Extended parameter – Enable group object after return of voltage
Options
No
Yes
Note: This object is only adjustable if the "Enable object" parameter is set to
"activated".
The parameter "Enable after return of voltage" exists to permit a defined behavior at the
"Enable" communication object after a return of bus voltage. A determination is made
here about whether a "1" ("enable") or a "0" ("blocked") is present on the enable object
after the return of bus voltage.
Note: If the logic of the enable function is set to "inverse", the behavior is also inverted
after the return of bus voltage, i.e. if the parameter "enable after return of bus voltage" is
set to "enable", and at the same time the "logic of the enable function" is parameterized
to "inverse", then the function will initially not be active after return of bus voltage. This
must first be activated via the receipt of an OFF telegram on the enable object.
