The SIMATIC ET 200pro FC‑2 distributed frequency converter is a compact frequency converter for standard drives which has the design of a SIMATIC ET 200pro module. Each SIMATIC ET 200pro FC‑2 frequency converter includes both the Control Unit as well as the Power Module in one unit. In addition, there is a backplane bus module for integrating the frequency converter in the SIMATIC ET 200pro system bus.

SIMATIC ET 200pro FC‑2 frequency converter

The SIMATIC ET 200pro FC‑2 frequency converter supplements the SIMATIC ET 200pro system range with distributed, speed-controlled drives. The frequency converter offers, in combination with the other modules of the modular SIMATIC ET 200pro system, solutions which have been exactly tailored to the plant/system and allows, through the combination of several frequency converters in one distributed station, ideal solutions when drives are operated in the same area or for the same purposes.

It is completely embedded in the SIMATIC ET 200pro system and offers all the system advantages such as cabinet-free installation, easy mounting on the module rack, reduction of the wiring outlay 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 SIMATIC ET 200pro station.

The certified STO safety function integrated as standard ensures 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.

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 a braking chopper and braking resistors. To ensure full motor protection, a temperature sensor of the PTC type, bimetal, KTY or Pt1000 can be connected. The integrated 180 V DC brake control at 400 V line voltage (U_line Г— 0.45 = brake voltage) allows the direct activation of a motor holding brake and makes a rectifier in the motor terminal box superfluous.

In combination with an SD memory card, the slot for the optional memory card can be used to save the parameter settings in order to facilitate fast replacement of modules with automatic reparameterization.

SIMATIC ET 200pro FC‑2 frequency converters use the control modes frequency control and sensorless vector control. The SIMATIC ET 200pro FC‑2 frequency converter also supports torque control, for example, for applications with mechanically coupled drives. The innovative power unit concept capable of energy recovery helps save energy.

Options for parameter assignment:

• STARTER, the graphical parameterization tool for Siemens drives
• The fieldbus
• A point-to-point connection via a mini USB interface
• The optical interface for connection of an IOP-2 Handheld

A parameter set download from the SIMATIC controller is also possible.
