Product Description:

The EFC5610-1K50-1P2-MDB-7P-NNNNN-L1NN frequency converter is produced by Bosch Rexroth Indramat as part of the EFC Frequency Converters series. It converts single-phase AC power into a variable three-phase output with adjustable frequency and voltage, allowing precise speed regulation of induction motors in automated machinery. This model serves general-purpose motion in pumps, fans, and conveyors where compact installation and straightforward setup are required. Adjustable output lets the connected motor match process demand more closely during acceleration, steady operation, and speed changes. It follows the EFC 5610 model designation and belongs to product line 02 within the series.

The converter accepts a mains supply of 200 V (AC 200…240 V ±10%), so it can operate on common low-voltage networks with moderate input variation. In heavy-duty service, it can drive motors up to 1.5 kW. The power stage is fed by a single-phase supply, which suits locations where three-phase utility power is not available. Motor control uses Standard Vector control (SVC), which supports stable low-speed operation and steady torque response under changing load. The integrated filter is rated class C3 for industrial areas, helping reduce conducted interference toward neighboring equipment.

Control logic resides on the Flex-Control board with standard I/O, matching the series configuration for basic machine integration. For functional safety, the drive provides Safe Torque Off (STO), which forces the output stage into a non-energized state during an emergency stop. Remote communication is available through Modbus, and parameters can be changed from the standard LCD display with potentiometer on the front panel. The front interface also provides direct local access to operating menus and routine adjustments. The housing has an IP 20 Cold Plate design and must be mounted on a conductive surface to transfer heat away from the power section. Frame size C keeps the unit compact and supports orderly cable routing inside small control cabinets.
