Product Description:

The EFC5610-0K40-3P4-MDB-7P-NNNNN-L1NN is a variable-speed drive unit produced by Bosch Rexroth Indramat and assigned to the EFC Frequency Converters series. As a standalone frequency converter, it modulates the supply frequency delivered to an induction or synchronous motor, allowing adjustable speed and energy-efficient operation in material handling, pump, and fan installations on factory floors. The device integrates easily into control cabinets and broader industrial automation architectures.

It is designed for supply networks that provide 400 V AC, with an allowable window from 380 to 480 volts so the converter can function on most industrial power systems. When loaded under the heavy-duty rating, it supports motors up to 0.4 kW, matching small conveyor or pump drives. The cooling surface follows the IP 20 Cold Plate category; heat is transferred to a mounting plate while the electronics remain finger-safe. To limit conducted interference, the built-in filter is specified for Industrial area, class C3, which is typical of large machinery lines. A certified Safe Torque Off circuit disconnects gate signals to the power stage, providing a hardware method for preventing unintended motion. Standard control configuration with the Flex-Control section and its integrated I/O simplifies wiring to sensors or relays without expansion modules.

Field integration is supported by the Modbus communication channel, which permits parameter access from PLCs and HMIs without proprietary gateways. Speed regulation is executed with Standard Vector control SVC, enabling stable torque at low frequencies while avoiding manual tuning. The mechanical envelope corresponds to frame size B, which determines the converter's height and mounting hole pattern inside a panel. Power is accepted and delivered through a three-phase bus, making the unit compatible with common industrial feeders. A standard LCD display equipped with a potentiometer supports local adjustments.
