Product Description:

The EFC5610-0K75-3P4-MDA-7P-NNNNN-L1NN is a variable-speed frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. It provides closed-loop speed regulation for three-phase induction motors in conveyors, pumps, and fans through standard vector control (SVC). The unit uses a Flex-Control section with standard I/O, giving five discrete inputs and built-in Modbus networking for connection to PLCs. This arrangement allows commands and feedback to share a single RS-485 channel, while local changes can be made from the front LCD panel with an integrated potentiometer. It supports both networked control and direct local adjustment from the same device.

With a width of 95 mm, a height of 166 mm, and a depth of 167 mm, the converter fits compact control enclosures. The control configuration follows the standard arrangement used for product line 02 models. It is designed for a three-phase supply of 400 V (AC 380…480 V -15% / +10%) and delivers a continuous output of 2.3 A to motors rated at 0.75 kW. For high-demand cycles, the drive can sustain 150% (60 s) overload and tolerate 200% (1 s) peak current without derating. An internal filter certified for industrial area class C3 limits conducted emissions, and the housing is protected to IP20 for panel installation. Its compact enclosure helps preserve usable space for wiring and airflow inside the cabinet.

The motion profile remains flexible because the closed-loop algorithm maintains a speed regulation range of 1:200, and the inverter can generate a starting torque of 200% (0.5 Hz) for breakaway loads. This combination helps the drive hold low-speed operation and start loads that resist initial movement. When machine safety is required, the integrated Safe Torque Off (STO) circuit disables power to the motor without a contactor. Frame size B aids heat dissipation, and the standard LCD with potentiometer allows on-site adjustment of acceleration ramps and other basic settings during setup.
