EFC5610-11K0-3P4-MDA-7P-DRNNN-L1NN

The Bosch Rexroth Indramat EFC5610-11K0-3P4-MDA-7P-DRNNN-L1NN frequency converter from the EFC Frequency Converters series offers 11.0 kW continuous power at a 400 V connection voltage with an integrated Modbus communication module. This model employs a standard vector motor control algorithm for precise speed and torque management across its 1:200 speed regulation range. Designed for space-saving installation, its compact design facilitates seamless integration between an EMC filter and an AC output choke in drive systems. Electrolytic capacitors and relay contacts are optimized for reliable switching, though frequent start-stops can gradually reduce their service life.

Performance features include an output efficiency of more than 95% and a digital frequency setting resolution of 0.01 Hz for high-precision applications. The unit implements Safe Torque OFF functionality and a DC braking time of 0 to 20 seconds, enabling controlled deceleration under load. Its three-phase supply connections can be ordered arbitrarily, provided a screened cable links the converter to the motor, and a mandatory five-minute isolation precedes every maintenance cycle. Bosch Rexroth Indramat backs the converter with a one-year warranty for manufacturing defects.

Robust protection functions guard against motor overload, surge current, short circuit and broken analog input wiring, while thermal dimensioning ensures stable operation up to 55 °C with derated data. The device delivers an output capacity of 16 kVA and automatically reduces output current at elevated carrier frequencies to maintain constant power dissipation in the inverter section. This internationally shippable converter meets industrial EMC requirements and is ready to serve demanding automation environments.
