Product Description:

The EFC3610-3K00-3P4-MDA-7P-NNNNN-NNNN is a frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. It is used in industrial automation to vary the speed of standard induction motors, matching mechanical demand and lowering energy use on conveyors, pumps, or fans. By converting fixed-frequency mains power into a variable output, the unit provides a compact drive element that fits easily into centralized control panels.

The converter accepts an input of 400 V (AC 380–480 V −15 % / +10 %), so it can connect directly to common factory distribution networks. Being wired for three phases helps keep motor torque smooth and reduces harmonic stress on the supply. The power stage supports 3.0 kW in heavy-duty service, enabling full-torque acceleration for typical 4-horsepower motors. Regulation is handled by enhanced V/Hz control; this scalar method maintains constant flux without feedback devices and provides predictable performance over the full frequency range. An enclosure rated IP 20 protects the electronics against accidental contact when the unit is installed inside a cabinet while still allowing adequate airflow for cooling.

For networked operation, the drive includes Modbus communication over RS-485, allowing speed setpoints, status bits, and parameter data to be exchanged with PLCs. Conducted emissions are limited by the integrated filter specified as industrial area, class C3, which meets wiring-length requirements typical of large machines. Overall size follows frame designation D, so mounting holes and cable clearances align with other EFC 3610 variants. Local setup is handled through a standard LCD display with potentiometer, while the Flex-Control section provides standard I/O for start commands, fault signals, and analog references. The control configuration is standard, and no additional safety function is included. The product is part of Line 02 of the series.
