2.1 The frequency converter
Description
The ET 200Pro FC is a compact frequency converter that is completely embedded in the
distributed I/O system of the ET 200pro. The individual components can be configured in
STEP 7 HW Config or integrated into other configuration systems using a GSD (device
master file).
The frequency converters are available in two versions:
Standard
Fail-safe
The frequency converter works with an input voltage of 3 AC 400 V 50/60 Hz and can be
used for 3-phase motors up to 1.1 KW, with temperature derating up to 1.5 KW.
Special features of the frequency converter
The power unit of the frequency converter feeds the braking energy from the motor back into
the line supply system. A braking resistor, which transforms energy accumulated during
regenerative operation into heat, is not necessary. The frequency converter can be operated
without a line reactor.
Commissioning and operation
The commissioning software STARTER is used for commissioning. It can be downloaded
from the Siemens homepage or ordered on a data carrier. It parameterizes the frequency
converter through a fieldbus or a point-to-point connection. You have the option of reading
the parameters for operating the frequency converter from the EEPROM of the frequency
converter or from a Micro Memory Card (MMC) that is inserted in the frequency converter. A
higher-level controller (e.g. SIMATIC S7) program is used to control the frequency converter.
