Product Description:

The EFC5610-18K5-3P4-MDA-7P-DRNNN-NNNN frequency converter is produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. It serves as a drive component for small to midsize automation cells by converting fixed-frequency three-phase input power into a variable output for motor speed control. This operating method helps reduce mechanical stress during startup and stopping while also supporting stable process behavior in conveyors, pumps, fans, and similar equipment. Its role in the system is to give the connected motor adjustable speed and torque without requiring a separate external speed-control device.

The drive uses Flex-Control with standard I/O, so digital and analog signals can be connected directly for routine control tasks. Its regulation method is standard vector control (SVC), which helps maintain useful torque at low speeds by monitoring motor current behavior during operation. Local parameter access is provided through a standard LCD display with a potentiometer, making it possible to view status information and adjust settings at the unit. Serial communication is handled through Modbus, allowing command and status data to move over a simple network link. The power section accepts 400 V AC (380 to 480 V, -15% / +10%) from a three-phase supply, which matches common industrial distribution systems.

An internal EMC filter for industrial areas, Class C3 helps limit conducted interference returning to the mains. The housing uses frame size G, which provides space for cooling airflow while keeping the enclosure suitable for panel mounting. In heavy-duty operation, the converter supports motors up to 18.5 kW, making it suitable for loads that need strong starting torque and stable speed control under changing demand. The enclosure is rated IP20, so the unit is intended for installation inside a cabinet where it is protected from accidental contact and outside contamination.
