Product Description:

The EFC3600-0K75-1P2-MDA-7P-NNNN is a variable-speed drive from Bosch Rexroth Indramat in the EFC Frequency Converters series. It is intended to regulate induction motor speed in compact pumping, conveying, and general automation equipment by varying output frequency and voltage. This control method helps the connected motor match process demand more closely than fixed-speed operation. This makes it suitable for small standalone machine sections that need repeatable speed regulation without a large drive platform.

Heavy-duty output is rated at 0.75 kW, giving the converter suitable capacity for small fans, pumps, and conveyors. The power section accepts AC 200–240 V ±10% and is designed for single-phase mains, which is useful where three-phase service is not available. Motor excitation is handled by Enhanced V/Hz control, a scalar method that maintains stable flux during load changes. That approach keeps operation straightforward for common induction motor applications. An onboard RS-485 interface supports Modbus, allowing parameter access and status monitoring through standard control systems. The standard control setup also provides adjustable acceleration and deceleration ramps, jog operation, and fault handling functions.

Local operation uses a standard LCD display with a potentiometer, which shows output frequency and allows direct speed adjustment from the front of the unit. The front panel can be used for basic setup and operating checks without separate accessories. Conducted emissions are limited by an integrated EMC filter rated Industrial area, class C3, reducing the need for additional line filtering in typical factory installations. The housing follows the compact B (1P) / C (3P) frame format used across the range, which helps cabinet layouts stay consistent between supply versions. The enclosure has a protection class of IP 20, so it provides finger-safe ventilation and is intended for installation inside a closed cabinet. Flex-Control I/O includes six digital inputs, one analog input, and one relay output for start, stop, and speed-reference signals.
