Product Description:

The EFC5610-1K50-3P4-MDB-NN-FCPNN-NNNN is produced by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. It is part of product line 02 in the EFC 5610 range. This unit functions as a variable-speed drive for industrial automation, converting fixed-frequency mains power into controlled output that matches process demands on pumps, fans, or material-handling motors.

The converter is designed for a nominal input of 400 V AC within a 380–480 V tolerance window and is wired to a three-phase supply. In heavy-duty mode, it supports up to 1.5 kW of motor power, so it can drive small and medium-frame induction motors under continuous mechanical load. An internal filter rated for Industrial area, class C3 limits conducted emissions so the unit can be installed in non-commercial environments without additional line chokes. Thermal dissipation takes place through a cold-plate heat sink with IP20 cold-plate protection, allowing installation inside a ventilated control cabinet while guarding against accidental contact with live parts.

Command and diagnostic data travel over Modbus, providing open communication with PLCs through the integrated standard control configuration. Torque and speed are handled by Standard Vector Control SVC, which maintains flux orientation for accurate motor regulation at low speeds. The control section uses a Flex-Control with standard I/O layout, giving discrete terminals for start, stop, and reference signals when fieldbus wiring is not required. The unit has no integrated keypad, so the housing uses a dust cover instead of a display. It also has no integrated safety function, so external safety relays must supervise critical axes. Mechanical dimensions correspond to frame size C, matching other devices that use the same mounting footprint.
