Parameters
4.2 Motor control
Control functions (e.g. direct starters, reversing starters) are used for controlling load
feeders. They are characterized by the following important features:
● Monitoring the switch-on / switch-off process
● Monitoring the ON / OFF status
● Tripping if a fault occurs.
SIMOCODE pro monitors these statuses using the "Feedback ON" auxiliary control input,
which is usually derived directly from the current flow in the main circuit, via the current
measuring modules.
All the necessary interlocks and logic operations for the respective applications are already
implemented in the control functions. Control functions include:
● Plugs for control commands ON <<, ON <, OFF, ON >, ON >> that are usually connected
with the "Enabled control command" sockets.
● Auxiliary control inputs (plugs), e.g. Feedback ON
● Sockets for
– Contactor controls QE1 to QE5.
– Displays (lamp controls) QL, QLS.
– Statuses, e.g. "Status - ON <<, Status - ON >>."
– Faults, e.g. "Fault - feedback (FB) ON," "Fault - antivalence."
● Settings, e.g. interlocking time, non-maintained command mode ON / OFF, etc.
● A logic component with all necessary interlocks and connections for the control function.
● Like control functions, the motor protection with its parameters and signals is active "at a
higher level in the background". Motor protection and thermistor protection are
independent functions that switch off the motor when activated via the control functions.
