Product Description:

The EFC5610-22K0-3P4-MDA-NN-NNNNN-L1NN is a variable-speed frequency converter built by Bosch Rexroth Indramat for the EFC Frequency Converters series. Within an automation cell, it modulates the supply to an induction motor so that speed and torque follow programmed setpoints, assisting pumps, fans, and conveyors that operate under changing duty cycles. The unit belongs to the EFC 5610 product line 02 and serves as a control component for machines that require adaptable three-phase power without external motor contactors.

Rated for 22.0 kW in heavy-duty mode, the converter matches medium-sized induction motors and draws from a nominal 400 V supply that may vary from 380 to 480 VAC (-15% / +10%). Because it accepts three phases, the input current stays balanced and harmonic stress is reduced. Speed regulation is handled by standard vector control SVC, a closed-loop method in the Flex-Control section with standard I/O. Machine safety is addressed through the integrated Safe Torque Off (STO) function, which removes energy from the motor circuit when the logic input is triggered and stops torque production without a mechanical brake. The front panel uses a dust cover instead of an HMI, so setup and parameter changes are handled through remote tools.

For electromagnetic compatibility in industrial cabinets, the integrated Industrial area, class C3 filter attenuates conducted emissions. An IP 20 housing shields the power section from solid ingress and supports cabinet mounting in clean environments. Field devices exchange data over Modbus, enabling parameter read and write functions with PLCs through the standard communication port. The mechanical footprint uses frame size G, so installation clearances match other drives with the same outline. This cabinet-mounted layout keeps the filter, communication port, and power section in one enclosure.
