Product Description:

The EFC3600-1K50-1P2-PDA-7P-NNNN frequency converter is manufactured by Bosch Rexroth Indramat and is part of the EFC Frequency Converters series. It is intended for cabinet mounting where variable-speed regulation of asynchronous motors is required in factory automation. By processing incoming mains power through its internal power stage, the unit delivers an adjustable output so pumps, fans, or conveyors can follow process demand more closely. This operating approach helps smooth starts, limit unnecessary motor speed, and support steady control in general machine applications. It is also useful where changing load conditions call for adjustable acceleration and stable motor operation.

Its control section uses a standard configuration with Flex-Control and standard I/O. Motor flux is managed by Enhanced V/Hz control, which provides a predictable voltage-to-frequency relationship for constant-torque and quadratic-torque loads. The converter connects to 200 to 240 V AC and is designed for single-phase feeders, making it suitable for installations where three-phase service is not available. In heavy-duty operation, the drive supports motors up to 1.5 kW. Electromagnetic emissions are limited by a filter intended for an industrial area, class C3 environment, and all components are housed in frame size C for a compact cabinet footprint.

The front panel uses a standard LCD display with a potentiometer, allowing operating values to be viewed while frequency is adjusted from the dial. The converter carries the EFC 3610 designation. Its enclosure has an IP 20 rating, which provides protection against accidental finger contact and makes enclosed panel installation appropriate where dust or moisture may be present. The visible display helps confirm operating status at the cabinet door, and the local dial offers a straightforward way to trim output frequency when the application allows manual adjustment.
