Glossary
Operating hours monitoring
The motor operating hours monitoring function enables the operating hours (service life) of a
motor to be recorded so that motor maintenance prompts can be generated in good time as
applicable.
Operation monitoring
SIMOCODE pro can monitor the operating hours and stop times of a motor and restrict the
number of startups in a defined time frame in order to avoid plant downtimes due to failed
motors caused by running or being stopped for too long.
Operational Protection Off (OPO)
The "Operational Protection Off (OPO)" function block puts the positioner into a safe position
and switches the motor off.
Operator panel with display (OPD)
The operator panel with display can be used as an alternative to the standard operator
panel (OP). It displays the current measured values, operating and diagnostic data, status
information for the motor feeder at the switchgear cabinet and the device-internal error log. It
also contains all the status LEDs that are present on the basic unit and facilitates access to
the system interface from outside the cabinet. Its keys can be used to control the motor and
to navigate the display menu.
Operator panel (OP)
The operator panel controls the motor feeder from the switchgear cabinet. It contains all the
status LEDs that are on the basic units, the "TEST/RESET" button and the external system
interface.
Organization block
Organization blocks form the interface between the CPU operating system and the user
program. The order in which the user program is processed is specified in the organization
blocks.
Overload protection
SIMOCODE pro protects three-phase or AC motors in accordance with IEC 60947-4-1
requirements. The trip class can be set to eight different settings ranging from CLASS 5 to
CLASS 40.
Pause time
The pause time is the specified time for the cooling down response of the motor when
tripped under normal operating conditions (not in the case of an overload trip). After this
interval, the thermal memory in SIMOCODE pro is erased and a new cold start is possible.
This means that many startups can be performed in a short space of time.
