Product Description:

The EFC5610-1K50-3P4-MDB-NN-FCPNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat and supplied within the EFC Frequency Converters series. As a variable-speed AC drive, it modulates output frequency to control induction motor speed in automated material-handling, pumping, and fan systems. Its Flex-Control section with standard I/O supports direct wiring to sensors and contactors, while the cold-plate chassis allows mounting to an external heat sink inside a control cabinet for efficient thermal transfer.

The unit operates on a supply of 400 V (AC 380...480 V -15% / +10%) and is intended for three-phase utility networks, so it can be installed on common industrial power buses without a transformer. Torque and speed are regulated through standard vector control (SVC), which provides slip compensation without requiring an encoder. Heavy-duty applications can draw up to 1.5 kW of mechanical output from the connected motor, with current and thermal limits managed internally by the drive. Parameter access and fieldbus communication are available through Modbus, which enables simple PLC integration over an RS-485 link. All power components are housed in frame size C, which keeps the mechanical footprint consistent with other drives in the same product line.

Functional safety is addressed by the hardware-gated Safe Torque Off (STO) channel, which disables gate firing so motor torque drops without opening the mains contactor. The enclosure is rated IP 20 Cold Plate, allowing finger-safe installation while transferring heat to the mounting surface rather than relying on its own fan. Conducted emissions are mitigated by the integrated filter classified for Industrial area, class C3, keeping switching noise within limits for non-public grids. A dust cover replaces the local keypad, and the standard control configuration is intended for operation through external control wiring.
