Product Description:

The EFC5610-11K0-3P4-MDB-7P-NNNNN-L1NN is a variable-speed drive in the EFC Frequency Converters series produced by Bosch Rexroth Indramat. As a frequency converter, it changes fixed AC mains power into adjustable output frequency and voltage so three-phase induction motors can match process demands more closely. The model belongs to the EFC 5610 product line and uses frame size F, which gives the unit a consistent mechanical footprint across the range. In automated machines, the drive supports speed regulation while reducing inrush stress and improving energy usage.

Its heavy-duty channel is rated for a motor shaft output of 11.0 kW, allowing the converter to operate mid-range pumps, fans, and conveyors without derating. The drive accepts an input supply of 400 V (AC 380...480 V -15% / +10%), and its internal rectification and modulation stages convert that three-phase power into a variable PWM output. The unit uses three-phase operation, so it connects directly to standard industrial distribution networks. Process controllers can send speed references through the integrated RS-485 port using Modbus, and the embedded Flex-Control section provides standard digital and analog I/O for standalone tasks. Motor flux is managed by standard vector control (SVC), which supports strong low-speed torque and stable acceleration without encoder feedback.

Electromagnetic compatibility is supported by a built-in filter rated for industrial area, Class C3, which helps limit conducted emissions on long motor leads. The converter mounts on a heat sink plate and uses an IP20 cold-plate design, so it is intended for installation inside a protective cabinet with forced-air or liquid cooling. A dual-channel safety circuit provides Safe Torque Off (STO), allowing immediate motor torque shutdown without mechanical relays. Parameter entry and real-time monitoring are handled through a front-mounted interface with a standard LCD display with a potentiometer for direct local adjustment.
