Product Description:

The EFC5610-22K0-3P4-MDA-7P-DRNNN-L1NN is a frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. It is part of the EFC 5610 model series and product line 02. Designed for three-phase induction motors, the unit regulates speed and torque in pumps, fans, and general-purpose machinery used in automated plants. Its control functions help match motor operation to changing process demand in variable-speed applications.

The converter operates from a supply range centered on 400 V (AC 380…480 V -15 % / +10 %), allowing installation on common industrial power systems. Under heavy-duty ratings, it can deliver 22.0 kW of shaft power, so motors up to that size can be driven without derating. The drive uses standard vector control (SVC), which separately regulates flux and torque components to improve low-speed performance over simple V/Hz methods. For functional safety, the integrated Safe Torque Off (STO) circuit removes gate power to the output stage and helps prevent unintended rotation during a stop condition. Conducted emissions are limited by an internal filter rated for Industrial area, class C3, which is suitable for cabinet-based industrial installations with shielded motor cables.

A built-in Modbus port supports register mapping for speed commands, diagnostics, and parameter updates over RS-485 networks. The plastic housing has a protection rating of IP 20, so the unit is intended for installation inside an enclosure while still protecting against accidental contact with live parts. Mechanical dimensions follow frame size G, giving a consistent mounting pattern for this power class in the series. Parameter access is provided through a Standard LCD display with potentiometer; the screen shows set points and fault codes, and the knob allows direct frequency adjustment from the front panel.
