Product Description:

Bosch Rexroth Indramat produces the EFC5610-4K00-3P4-MDA-7P-NNNNN-NNNN, a member of the EFC Frequency Converters series. The unit is a frequency converter used to vary the speed of induction motors and reduce energy use in automated machinery such as conveyors, pumps, fans, and other general-purpose equipment. Its compact format supports cabinet installation where available space is limited, while still providing adjustable motor control for applications that need stable operation across changing load conditions. It is well suited to systems that require flexible speed control, straightforward wiring, and integration with common industrial control hardware.

The converter accepts a supply of 400 V (AC 380–480 V -15% / +10%), making it compatible with common industrial mains. Under heavy-duty conditions it can drive motors up to 4.0 kW, providing constant torque across a broad speed range. Regulation is handled by standard vector control (SVC), which estimates motor flux in real time to improve low-speed performance without encoder feedback. This control method helps maintain smoother speed response during load changes and supports induction motors that do not use separate position feedback devices. The enclosure has an IP20 rating, so it is intended for installation inside a control cabinet rather than in an exposed machine location. The unit operates on three-phase power, which helps distribute input current more evenly across the supply. A Flex-Control section with standard I/O supports start, stop, fault reset, analog reference, and relay signaling.

Setup and monitoring are available through Modbus, allowing parameter access over a two-wire serial link from a host controller or local interface. For electromagnetic compatibility, the integrated filter meets Class C3 for industrial areas, which suits typical factory installations that use dedicated control cabinets and industrial power distribution. The mechanical layout uses frame size D, so mounting points and cooling space follow the dimensions used for this housing size in the product line. Local adjustments can be made with the standard LCD display with potentiometer, which provides direct access to operating values and speed reference changes at the front of the unit. The display also allows quick review of operating status, output frequency, and fault messages without requiring a separate external tool. The control configuration is standard and is intended for baseline variable-speed duties in general industrial applications.
