Product Description:

The EFC5610-1K50-3P4-MDB-7P-NNNNN-L1NN frequency converter is produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. In motor control cabinets, this AC drive regulates induction motor speed to match process demand, which helps reduce energy use and mechanical stress in automated equipment. By integrating command, protection, and power electronics into one compact housing, the EFC5610-1K50-3P4-MDB-7P-NNNNN-L1NN serves as a scalable drive for pumps, fans, and conveyor modules. Its compact form also supports installation in cabinets where mounting space is limited.

The unit accepts a supply of 400 V (AC 380…480 V -15 % / +10 %) across three phases, giving it the range needed for common industrial mains variation. Under heavy-duty operation, it is rated for 1.5 kW motor output. The built-in Standard Vector control SVC algorithm maintains constant torque over a wide speed range by adjusting voltage and frequency as load conditions change. For installation in industrial switch rooms, the integrated industrial area, class C3 EMC filter reduces conducted emissions and helps the cabinet meet EN 61800-3 limits without external components.

Parameter access and diagnostics are handled over the Modbus serial protocol, allowing the converter to exchange commands and status data with plant PLCs without proprietary gateways. A dedicated digital input enables the Safe Torque Off (STO) function, so the power stage can be disabled through a safety relay without auxiliary contactors. Mechanical integration is simplified by the compact frame size C, and thermal coupling is provided by the IP 20 Cold Plate construction that bolts directly to a chilled panel or heat sink. The Flex-Control I/O section and LCD keypad support local setup and routine status review at the cabinet.
