Product Description:

The EFC3600-1K50-3P4-MDA-7P-NNNN is a frequency converter produced by Bosch Rexroth Indramat for the EFC Frequency Converters series. Positioned within the EFC 3610 line, it adjusts induction motor speed to match process loads in manufacturing cells and material-handling equipment. The unit belongs to the frequency converter product group and arrives with a standard control configuration. Its control section follows the Flex-Control design and uses standard I/O terminals so that run, direction, fault, and analog speed references can be wired directly to a PLC or relay set.

The power stage accepts a mains input of 400 V (AC 380–480 V -15% / +10%) delivered through a three-phase supply, allowing the converter to be installed on typical plant distribution networks without an isolation transformer. Motor torque is generated under enhanced V/Hz control, an open-loop algorithm that improves low-speed stability compared with basic scalar drives. For heavy-duty operation, the output supports up to 1.5 kW of motor power, so fans, pumps, or conveyors within that rating can be started and accelerated without derating. Conducted emissions are limited by an internal EMC filter rated class C3, which is intended for industrial environments where higher permissible line noise is expected.

The housing carries an IP 20 rating, indicating finger-safe openings yet requiring installation inside a cabinet for full dust protection. Serial supervision and parameter download are available through Modbus, enabling simple integration with HMIs and remote diagnostics. Overall envelope dimensions correspond to frame size C, which simplifies panel layout because mounting hole positions follow a consistent Bosch Rexroth pattern. Daily adjustments can be performed from the front-mounted standard LCD display with potentiometer, which provides local speed reference and status feedback without connecting a programming tool.
