Product Description:
The EFC3610-7K50-3P4-MDA-NN-NNNNN-NNNN frequency converter is produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. It converts fixed grid power into variable frequency and voltage so that asynchronous motors can run at the speed the application requires. By inserting this unit between the plant mains and the motor, automated systems such as pumps, fans, and indexing conveyors gain straightforward speed regulation without adding servo complexity. Because motor speed can be adjusted electronically, the drive can also reduce mechanical stress during startup and better match process demand during changing operating conditions.
This model accepts a mains window of 380–480 V AC, allowing operation on regional 400 V networks with a -15% to +10% tolerance. Its input is wired in a three-phase configuration, which distributes current evenly and minimizes line distortion. Under heavy-duty ratings, the converter can deliver up to 7.5 kW of mechanical power to the motor shaft, enabling medium-sized machines to start and accelerate under load. Motor flux is managed by enhanced V/Hz control; this open-loop scheme keeps the voltage-to-frequency ratio constant so torque remains stable across the speed range. For plant networking, an onboard Modbus interface carries run, stop, and parameter data to the PLC without extra option cards. An integrated EMC filter qualified for class C3 limits conducted emissions, making the drive suitable for industrial areas that permit higher interference levels than residential zones. This control approach suits general-purpose machinery that needs reliable speed adjustment without separate feedback hardware.
The enclosure has an IP20 rating, meaning fingers are protected from live parts but the drive must be mounted in a clean panel. All power components are packed into frame size E, keeping height and depth consistent with other 3610 units for easy retrofits. The control section follows the Flex-Control layout with standard digital and analog I/O, so start, fault reset, and speed reference signals can be wired directly to terminal strips without additional breakout boards. This arrangement supports panel installations where orderly terminal access and protected internal placement are required.
