Product Description:

The EFC3600-4K00-3P4-PDA-7P-NNNN frequency converter is manufactured by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. This unit is a variable-speed drive intended to regulate induction motor speed in automated conveyor, pump, and fan applications across general industry. The design targets processing, packaging, and material-handling cells where space and wiring simplicity are critical. By modulating output frequency and voltage, the converter allows process equipment to match load demand, reduce energy consumption, and soften mechanical stress on downstream components.

For electrical integration, the converter operates on a 400 V three-phase supply that can vary from 380 to 480 V within a -15%/+10% tolerance. Under heavy-duty loading, it delivers 4.0 kW of motor power, matching typical 5-horsepower machine sections without derating. Torque production is regulated through Enhanced V/Hz control, a scalar method that adjusts voltage in proportion to frequency to maintain magnetizing flux at low speeds. The input side expects a three-phase mains feed to balance current across the power section, while the housing is rated IP 20, which provides finger-safe openings but no splash protection.

Mechanical layout corresponds to Frame Size D, so mounting holes and enclosure depth align with other drives in the 22 cm class. The integrated EMC filter is rated for industrial area, Class C3, which limits conducted emissions on long motor cables typically found in factory power grids. Control electronics follow the Flex-Control with Standard I/O design, providing discrete terminals for run, direction, and fault signals without extra option cards. Parameter access is handled through a Standard LCD display with potentiometer, allowing on-site speed trimming and menu navigation. The drive is part of the EFC 3610 model subset.
