Product Description:

The EFC3600-0K40-1P2-MDA-7P-NNNN frequency converter is produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. It belongs to the EFC 3610 model group and is intended to vary induction motor speed in small industrial machines by adjusting supply frequency and voltage. Integrated power electronics and a Flex-Control section let the unit act as the link between 200 V single-phase mains and the driven load in applications such as fans, pumps, and compact conveyors.

Electrical parameters describe how the converter interfaces with the supply and motor. A single-phase 200 to 240 V AC input feeds a rectifier sized for a 5.8 A rated current, while the inverter delivers up to 0.4 kW of output power under heavy-duty conditions. Frequency is generated with 0.01 Hz digital resolution across the 1:50 regulation band, and the output can be driven as high as 400 Hz. Protection against dust contact is provided by the IP20 housing. Control tasks are handled through Enhanced V/Hz logic configured in Standard mode, and the Flex-Control section exposes conventional I/O together with Modbus for networked commands. An internal brake chopper works with a 400 Ω / 100 W resistor for dynamic deceleration, and an industrial-grade Class C3 filter limits conducted emissions. A front LCD with potentiometer, frame size B profile, and 4.5 mm M4 mounting points simplify panel integration. The unit operates between -10 °C and 50 °C without derating.

During operation, the IGBT bridge switches at up to 15 kHz, limiting motor acoustic noise while sustaining torque. At 3 Hz it can deliver 150% rated torque to start high-inertia loads, and once at speed it supplies a continuous 2.3 A RMS output that corresponds to 0.8 kVA of apparent power. These figures are shown on the LCD and can be reported over Modbus for remote diagnostics. For long-term reliability, the electronics may be stored between -20 °C and 60 °C before installation.
