Bosch Rexroth VFC 3610 series frequency converters are a new, cost-effective series of frequency converters that meet the high demands of today's developing market. Distinctive feature The new series has a modular design that allows you to adapt to almost any customer requirements. These inverters will find their application in ventilation, heating and air conditioning systems, textile industry, woodworking, conveyors and air compressors.
"Bosch Rexroth"– is a leading group of companies in the fields of hydraulics, pneumatics, control systems and drive technologies. The subsidiary Rexroth specializes in control systems and electric drives and is a global benchmark in this field.
The frequency converter from Bosch Rexroth is a new economical model suitable for most applications. The Bosch Rexroth Fe Series frequency converter has been designed for use in harsh industrial environments in Open-Loop applications.
For optimal performance when various modes Users are offered two options for the Bosch Rexroth Fe series frequency converter:
- G-Series of frequency converters - for applications in areas with higher overload capacity (belt conveyors, conveyors, mixers or extruders);
- P-Series frequency converters – for applications with higher continuous load capacity (pumps, fans or crushers).
Frequency converter (frequency converter or “frequency converter”) is a device for changing the frequency of electrical voltage (current). It consists of a rectifier that converts AC to constant, and an inverter (usually with PWM), converting D.C. into variable.

Features of Bosch Rexroth Fe series frequency converters
Frequency converter programmed using the special software Rexroth Converter PC 4. Rexroth Converter PC 4 is an intuitive software for easier and faster parameterization and commissioning of several Fes of the same or similar configuration. The parameters are set using a PC and then written to the frequency converter via a serial RS485 interface.
Additional equipment
Optionally available for the Fe frequency converter:
- EMC filter that ensures compliance with EMC requirements and suppresses leakage currents caused by conductor capacitance;
- Line choke, which reduces high-frequency harmonics of the mains current, protects the frequency converter from the negative influences of the network and prevents the converter from having a reverse effect on the supply network;
- dU/dt filter. Steep edges of output voltage signals in modern converters in combination with long cable Motor connections often result in transients that cause overvoltages at the motor terminals. By installing a dU/dt filter at the converter output, it is possible to reduce this effect and also reduce leakage currents in the motor cable.
- Braking module (chopper). Required in frequency converters with a rated power of more than 15 kW to control the braking resistor.
- Braking resistor. To absorb braking energy from frequency converters in regenerative mode, braking resistors with different permissible power inputs are available to choose from.
- Remote operator console. Thanks to a separate remote control panel, convenient servicing of frequency converters located in a closed control cabinet is possible. For connection there are cables 1 m and 3 m long.
- PROFIBUS adapter. The PROFIBUS adapter converts the RS485 Fe interface to the PROFIBUS standard and allows communication with a higher-level machine control system. Installation of the adapter is carried out by simply snapping onto the DIN rail.
