Product Description:

The EFC3610-5K50-3P4-MDA-7P-NNNNN-NNNN is a frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. The device changes fixed-frequency plant power into an adjustable output so that industrial drives can run at the speed required by the process. Its EFC 3610 platform supports standardized variable-speed control in conveyors, pumps, and fans where operating demand changes during use.

The unit is designed for a supply of 400 V AC (380–480 V ±10%) across three phases, so it can handle common industrial line levels without tap changers. Under heavy-duty loading, it delivers 5.5 kW of shaft power, matching mid-frame induction motors in material-handling areas. Speed modulation is produced by the drive’s Enhanced V/Hz control, which helps keep motor flux stable from low speed to rated speed. A standard control configuration with the Flex-Control section provides standard I/O for direct start, stop, and analog reference signals. Enclosure integrity is rated at IP 20, so live parts remain finger-safe inside a ventilated cabinet. The drive has no integrated safety function, so external contactors or separate STO hardware must be added when the application requires power isolation.

Parameter entry and local monitoring are handled by a standard LCD display with potentiometer, allowing on-panel frequency adjustment without external tools. For fieldbus wiring, the converter supports Modbus, giving basic register access to status words and setpoints over shielded RS-485 links. Electromagnetic compatibility in production plants is addressed by an integrated filter rated for industrial area, class C3, so conducted emissions stay below machine-room limits. Mechanical proportions follow frame size E, which keeps mounting patterns and cooling-air requirements consistent across drives in the same power class. This arrangement suits ventilated control cabinets that use direct operator access and simple serial communication.
