Glossary
Control functions
Control functions (e.g. direct-on-line starters, reversing starters) are used for controlling load
feeders. They are characterized by the following important features:
● Monitoring the switch-on / switch-off process (no current flows in the main circuit without
the ON command)
● Monitoring the OFF state (no current flows in the main circuit without the ON command)
● Monitoring the ON status
● Tripping if a fault occurs.
Control stations
Control stations are places from which control commands are issued to the motor. The
"Control Stations" function block is used for administration, switching and prioritization of
these different control stations. SIMOCODE pro allows parallel administration of up to four
different control stations. Dependent on the control function, up to 5 different control
commands can be transmitted from every control station to SIMOCODE pro.
● Local control, in the direct vicinity of the motor. Control commands via pushbuttons.
● PLC/PCS, switching commands are issued by the automation system (remote).
● PC, control commands are issued via an operator control and monitoring station or via
PROFIBUS DPV1 with SIMOCODE ES (TIA Portal).
● Operator panel / operator panel with display, control commands are issued via the
buttons of the operator panel / operator panel with display in the switchgear cabinet door.
Cooling down period
The cooling down period is the amount of time that must elapse before an overload trip can
be reset. This is usually 5 minutes. Supply voltage failures of SIMOCODE pro during this
time extend the specified time correspondingly.
Cos phi monitoring
Cos phi monitoring monitors the load condition of inductive loads. The main field of
application is for asynchronous motors in 1-phase or 3-phase networks with loads that
fluctuate significantly. The power factor (cos phi) is measured by evaluating the phase
displacement between the voltage and current in a phase.
Current measuring module (IM)
Current measuring modules are used together with the basic units. The current measuring
module must be selected according to the current setting to be monitored (rated operating
current of the motor). The current measuring modules cover current ranges between 0.3 A
and 630 A, with intermediate transformers up to 820 A.
