Product Description:

The EFC5610-18K5-3P4-MDA-7P-NNNNN-NNNN is a frequency converter produced by Bosch Rexroth Indramat in the EFC Frequency Converters series. It adjusts motor speed by converting a fixed line input into a variable output frequency for energy-efficient control of three-phase induction motors in conveyors, pumps, fans, and other automation equipment. This type of drive is useful where process speed must follow changing load conditions or production demand instead of running at one constant motor speed. The unit belongs to product line 02 and the EFC 5610 subseries. Its layout is intended for cabinet-mounted installations that use standard wiring practices and conventional external control circuits.

Under heavy-duty operation, the converter supports a motor power of 18.5 kW, so it can be matched with motors in that power class without derating. It accepts a 400 V AC (380 to 480 V, -15%/+10%) three-phase supply, which allows direct connection to common industrial power systems. Speed and torque are regulated by Standard Vector control SVC, providing stable motor control without requiring an encoder. This control method helps the drive maintain smooth acceleration and steady running across typical industrial load changes. Parameter access and remote commands are available through Modbus, and the control section includes conventional I/O for hard-wired start, stop, and reference signals.

The converter uses frame size G, which standardizes mounting points and cable entry for this output class. An internal EMC filter rated for Industrial area, class C3 helps reduce conducted emissions on the supply and motor connections. Local operation is provided by a Standard LCD display with potentiometer, allowing parameter entry and speed adjustment directly at the drive. The display can also show operating values and status information during normal use. The enclosure has an IP20 protection class, so the unit is intended for installation inside a control cabinet.
