12.4 Operational Protection OFF (OPO)
Safety information
Note
A "Trip - Operational Protection Off (OPO)" fault message is not generated if the "OPO"
command attempts to run the Positioner to the end position in which it is already in, or to
which it is heading.
Note
No other control command (counter command or stop command) is carried out while
"Operational Protection Off (OPO)" is active.
Note
The "Trip - Operation Protection Off (OPO)" fault message must be acknowledged using the
open or closed control command, depending on the present "OPO" end position.
Note
Acknowledgement is carried out even if the desired end position has not yet been reached.
Note
The fault message is available as diagnosis via PROFINET.
Response to other Control Functions:
For other control functions, the following scenarios can be differentiated between for OPO:
● Motor in operation: The motor is switched off with a "Trip - Operational Protection Off
(OPO)" fault.
● The motor is off. Initially no fault. The "Trip - Operational Protection Off (OPO)" fault only
occurs when an "ON Command" is issued.
