Product Description:

The EFC3610-0K40-1P2-MDA-7P-NNNNN-NNNN is a compact frequency converter manufactured by Bosch Rexroth Indramat within the EFC Frequency Converters series. Intended for cabinet mounting, the unit modulates the voltage and frequency delivered to an induction motor so that conveyor sections, pumps, or fans can run at the speed demanded by a control system. By adjusting motor speed instead of relying on mechanical throttling, the converter supports efficient operation in small machinery platforms where stable drive regulation is required. It also helps the connected motor start and run more smoothly in light-duty automation applications.

With a heavy-duty motor rating of 0.4 kW, the drive is suited to fractional-horsepower applications that demand continuous torque across a broad operating range. It accepts a mains supply of 200 to 240 V AC and rectifies this input internally, so field wiring is simplified because no three-phase line is required at the supply side. The configuration remains single phase on the input while three-phase output is synthesized for the motor terminals. A housing protection level of IP 20 limits the unit to clean, closed enclosures, and the built-in filter meets industrial area class C3 limits to reduce conducted emissions on the plant supply. This arrangement fits smaller control cabinets where available power service is limited but variable motor operation is still needed.

For system integration, the converter presents a Modbus interface that exchanges parameters with PLCs without proprietary software. Speed generation is based on Enhanced V/Hz control, providing finer voltage compensation at low frequencies than basic scalar modes. Operators can view status and setpoints on the front-mounted standard LCD display with potentiometer, while discrete and analog commands enter through the Flex-Control section with standard I/O. The compact housing fits within frame size B, which helps conserve panel space for neighboring electrical components. Local display access and network communication support both direct adjustment at the drive and routine supervision from a higher-level control system.
