Product Description:

The EFC5610-22K0-3P4-MDA-7P-NNNNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. It is part of the EFC 5610 model range and product line 02, and it is installed between the mains supply and an AC motor to regulate speed and torque through variable-frequency output. By providing closed-loop control for industrial pumps, fans, and conveyors, it helps optimize energy use and maintain consistent process variables on production lines.

The converter accepts a supply of 400 V (AC 380…480 V −15% / +10%) across a three-phase input and feeds a power stage sized for 22.0 kW heavy-duty motor loads. Within this electrical window, standard vector control (SVC) adjusts flux and torque in real time, delivering stable speed at low frequencies. Networked command and diagnostic data travel over Modbus, so the unit can be polled directly by a PLC without extra gateways. Internally, the Flex-Control section with standard I/O offers configurable digital and analog terminals, and the default control setup supports straightforward operation. A G frame size housing facilitates cabinet planning and leaves space for cabling and braking resistors inside the enclosure.

Installation considerations focus on protection, compliance, and the operator interface. The converter carries an enclosure rating of IP20, meaning it has touch-safe openings but no sealing against liquids, which suits indoor switchgear cabinets. To limit conducted emissions, it integrates an EMC filter certified for industrial areas, class C3 environments. Functional safety is covered by Safe Torque Off (STO), which removes drive energy when the monitored circuit opens. Operators adjust parameters through a standard LCD display with potentiometer, and status LEDs mirror the drive state for quick troubleshooting.
