Product Description:

Bosch Rexroth Indramat manufactures the EFC3600-0K75-3P4-MDA-7P-NNNN frequency converter as part of the EFC Frequency Converters series. Within the EFC 3610 model subset, this unit functions as a variable-speed drive that regulates motor voltage and frequency in automated machinery, helping match torque to process demand and lower energy consumption across pumps, conveyors, and compact material-handling workstations. It is suited for compact industrial systems that need adjustable motor speed without the space requirements of a larger inverter. By varying output frequency, it can support smoother starts and more stable operation on light-duty machine axes. The mechanical outline corresponds to Frame Size B, giving consistent mounting dimensions within the product group.

The converter accepts a supply of 400 V (AC 380…480 V -15 % / +10 %) and is designed for a three-phase network, which supports balanced line currents in industrial switchgear. In Heavy-Duty operation, it supports motors up to 0.75 kW, allowing reliable acceleration of small fans or indexing tables without derating. Output is modulated with Enhanced V/Hz control, an open-loop method that maintains air-gap flux at reduced speeds for consistent torque. The housing meets the IP 20 protection class, so installation inside a closed electrical cabinet is required. A standard control configuration is implemented, and the control section uses Flex-Control architecture with standard I/O terminals for digital commands and analog speed references. This layout supports straightforward connection to basic machine controls where simple run, stop, and speed signals are used.

User interaction is provided by the Standard LCD display with potentiometer, which allows local parameter entry, status viewing, and manual frequency trimming. Remote supervision is available through Modbus communication, enabling setpoint updates and fault diagnostics over an RS-485 link. Conducted emissions are limited by an integrated EMC filter rated for Industrial area, class C3, making the unit suitable for factory environments where higher switching noise is permissible. This arrangement allows both local access at the drive and network-based monitoring from a higher-level control system.
