Product Description:

The EFC5610-18K5-3P4-MDA-NN-NNNNN-L1NN is a frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. As a member of the EFC 5610 platform, it is installed between the mains supply and an induction or synchronous motor to regulate speed and torque for automated machinery, conveying equipment, or process pumps. By varying output frequency, it helps reduce energy use and match motor performance to real-time process demands in industrial automation lines. This operating role makes the unit suitable for applications that need smooth acceleration, controlled deceleration, and adaptable throughput during changing process conditions.

Electrically, the drive accepts a nominal input of 400 V AC across three phases, with an allowable supply range from 380 to 480 V. In heavy-duty mode, the unit can deliver 18.5 kW of shaft power when paired with the appropriate motor. Torque regulation is achieved by standard vector control SVC, allowing accurate speed control without an encoder. The mechanical layout corresponds to frame size G, which suits panel installation. The converter uses a standard control configuration with Flex-Control and standard I/O, so discrete signals, analog references, and relay outputs can be connected directly to external control devices. This arrangement supports straightforward integration with common automation systems.

Environmental and system interface requirements are handled by an IP 20 housing intended for closed electrical cabinets. The integrated Modbus port supports parameter access and remote start-stop commands, and the drive includes an industrial-area Class C3 filter that attenuates conducted emissions on the supply lines. A functional safety channel provides Safe Torque Off (STO) to remove drive torque without cycling the mains contactor. Local status is viewed through a dust-cover plate instead of an integrated display, and the product is part of line code 02.
