ET 200pro FC Frequency Converter Siemens

Область применения


  • The frequency converter controls the speed of asynchronous motors steplessly
  • The modular, service-friendly concept of the frequency converter is ideally suited to manufacturing processes with high plant standstill costs
  • Optimal solutions can be created using several frequency converters combined in one distributed station when drives are operated in the same area or for the same purposes.
  • The frequency converter handles frequency control for simple applications as well as vector control for more complex drive tasks. It also handles the optimal control of a motor brake, if used.
  • The converter also supports torque control, for example, for applications with mechanically coupled drives.
  • The advantages of line-commutated power regeneration are primarily evident in continuous regenerative operation. Examples include unwinding units, lowering of loads, or dynamic braking of large centrifugal masses.
  • The integral safety functions significantly reduce the overhead for drive solutions in plant sections where there is a hazard potential. Additional savings can be made thanks to sensorless speed monitoring of standard asynchronous motors.

ET 200pro FC frequency converter with backplane bus module and mounting rail

Особенности


  • The frequency converter is completely integrated into the ET 200pro system and offers all the system advantages such as cabinet-free installation, easy mounting on the module carrier, reduction of the wiring overhead due to self-assembling communication and supply rails in the backplane bus, comprehensive diagnostic mechanisms and high availability thanks to replaceability without affecting other modules in the ET 200pro station.
  • The load voltage is routed to downstream frequency converters or motor starters with minimal installation costs through pre-assembled jumper plugs. The maximum current carrying capacity of the jumper plugs is 25 A.
  • Easy combination and expansion of converter functionality using I/O modules or RSM isolator modules within the distributed station
  • Input for PTC/KTY encoder for comprehensive motor protection
  • The integral 180 V DC brake control makes the rectifier in the motor terminal box superfluous
  • Slot for optional memory card (MMC) to save the parameter settings for fast replacement of modules with automatic reparameterization
  • Available control modes: Frequency control, sensorless vector control or torque control
  • STARTER, the graphical parameterization tool for Siemens drives, is used to set the parameters either over the connected fieldbus or over a point-to-point connection
    Note: Access to the frequency converter over the bus is not possible using STARTER when a CPU is located between the PC and the frequency converter. This also applies to the IM154-8 CPU.
  • Active and dynamic braking of the motor is possible without incurring any additional costs. The generated braking energy is fed back into the power supply, so there is no need for braking choppers and pulse resistors.
  • The fail-safe version of the frequency converter offers autonomous, certified safety functions that ensure that persons and machines are protected from the dangerous movement of machines. Integration of the safety system into the drive also simplifies the machine architecture and supports system-wide diagnostics.
  • Local activation of the failsafe functions of the frequency converter with the Safety Local Isolator Module F-RSM or via fieldbus with the F-Switch PROFIsafe module.
