Product Description:

The EFC5610-2K20-3P2-MDA-7P-DRNNN-L1NN frequency converter is produced by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. It sits between the plant mains and an AC motor, converting fixed-frequency supply power into a variable frequency and voltage output. This function lets automated conveyors, pumps, and material-handling stations match motor speed to process demand while reducing energy consumption and mechanical wear. It is well suited to applications that need adjustable motor speed without relying on mechanical throttling or stepped starters.

Its heavy-duty output is rated at 2.2 kW, allowing the drive to run small to mid-sized induction motors without derating. The input window spans 200 to 240 V AC, so the converter can be wired to standard 200 V class industrial grids. The converter uses three-phase power on both the line and motor sides, which helps balance current and reduce harmonic stress. Motor flux is governed by standard vector control (SVC), enabling stable torque response even at low speeds. To integrate with supervisory controllers, the device communicates over Modbus, allowing basic start, stop, and parameter write commands to pass over a two-wire serial link. Internal filtering meets Class C3 for industrial environments, so additional external RFI components are not required when cabinet mounted.

Operational settings are entered through a standard LCD display with potentiometer, and the control panel sits on a Frame Size D housing that matches the EFC 5610 mechanical grid. This layout allows local access to speed references and parameter menus from the front of the unit. Internally, the converter follows the standard control configuration and uses the Flex-Control with Standard I/O section, so six digital inputs, two analog channels, and a relay output are present for stand-alone logic. The housing has an IP 20 rating for clean cabinet interiors, and the integrated safety circuit provides Safe Torque Off (STO) to disable motor torque.
