Product Description:

The EFC5610-0K75-3P4-MDA-7P-NNNNN-NNNN frequency converter is produced by Bosch Rexroth Indramat for the EFC Frequency Converters series. It belongs to the EFC 5610 range and product line 02, where it is used for variable-speed control of induction motors in industrial equipment. In operation, the unit adjusts output frequency and voltage so motor speed and torque respond to changing process demand. This makes it suitable for conveyors, pumps, fans, and similar machinery that benefits from steady control and reduced mechanical stress. Because the inverter changes motor output electronically, the connected machine can ramp more smoothly than with direct line starting.

For motor duty, the drive is rated at 0.75 kW. It accepts a nominal input of 400 V AC across a 380 to 480 V range, and the housing has an IP 20 protection level, so it is intended for installation inside an enclosure. Motor control uses Standard Vector control SVC, which supports stable speed regulation under changing load. Communication is available through Modbus, allowing an external controller or operator interface to exchange command, status, and parameter data with the drive. A standard LCD display with an integrated potentiometer supports local adjustment and basic status viewing without requiring a separate handheld interface.

The control section uses Flex-Control with Standard I/O, providing terminal resources for common machine signals and routine integration tasks. Its three-phase power stage is paired with an EMC filter rated to class C3, which helps limit conducted emissions in industrial installations. This arrangement supports common run, stop, fault, and analog reference signals without requiring an added expansion card. The compact Frame size B housing supports installation in space-conscious panels, and external safety hardware is required when a machine needs STO or SIL-based shutdown. The converter is supplied in a standard configuration for basic variable-speed applications.
