© Siemens 2022 Monitoring and control devices SIMOCODE 3UF motor management and control devices SIMOCODE pro 3UF7 motor management and control devices General data Benefits General customer benefits Integrating the whole motor feeder into the process control by means of PROFIBUS DP, PROFINET/OPC UA, Modbus RTU or EtherNet/IP significantly reduces the wiring between the motor feeder and the PLC Decentralization of the automated processes by means of configurable control and monitoring functions in the feeder saves resources in the automation system and ensures full functionality and protection of the feeder even if the I&C or bus system fails The acquisition and monitoring of operating, service and diagnostics data in the feeder and process control system increases plant availability as well as maintenance and service-friendliness The high degree of modularity allows users to perfectly implement their plant-specific requirements for each motor feeder The SIMOCODE pro system offers functionally graded and space-saving solutions for each customer application The replacement of the control circuit hardware with integrated control functions decreases the number of hardware components and wiring required and in this way limits stock keeping costs and potential wiring errors The use of electronic full motor protection permits better utilization of the motors and ensures long-term stability of the tripping characteristic and reliable tripping even after years of service Thanks to the precision of the current, voltage, power and energy measurements (especially those acquired by the 2 nd -generation current/voltage measuring modules), costs can be internally allocated with a high degree of accuracy Recording of measuring curves SIMOCODE pro can record measuring curves and therefore is able, for example, to present the progression of motor current during motor startup.
Flexible motor control implemented with integrated control functions (instead of comprehensive hardware interlocks) Many predefined motor control functions have already been integrated into SIMOCODE pro, including all necessary logic operations and interlocks:
Overload relays Direct-on-line and reversing starters Wye/delta starters (also with direction reversal) Two speeds, motors with separate windings (pole-changing starter); also with direction reversal Two speeds, motors with separate Dahlander windings (also with direction reversal) Positioner actuation Solenoid valve actuation Actuation of a motor starter protector Soft starter actuation (also with direction reversal) These control functions are predefined in SIMOCODE pro and can be freely assigned to the inputs and outputs of the device (including the PROFIBUS/PROFINET process image).
These predefined control functions can also be flexibly adapted to each customized configuration of a motor feeder by means of freely configurable logic modules (truth tables, counters, timers, edge evaluation, etc.) and with the help of standard functions (power failure monitoring, emergency start, external faults, etc.), without additional auxiliary relays being necessary in the control circuit. Multifunctional, electronic full motor protection for rated motor currents up to 820 A SIMOCODE pro makes a lot of additional hardware and wiring in the control circuit unnecessary, which results in a high level of standardization of the motor feeder in terms of its design and circuit diagrams.
SIMOCODE pro offers comprehensive protection of the motor feeder by means of a combination of different, multi-step and delayable protection and monitoring functions: Inverse-time delayed solid-state overload protection (CLASS 5E to 40E) Thermistor motor protection Phase failure/asymmetry protection Stall protection Monitoring of adjustable limit values for the motor current Voltage and power monitoring Monitoring of the power factor (motor idling/load shedding) Ground-fault monitoring Temperature monitoring, e.g. via Pt100/Pt1000 Monitoring of operating hours, downtime and number of starts, etc. 10/8 Siemens IC 10 · 2022 10
