Product Description:

The EFC3610-0K75-1P2-MDA-NN-NNNNN-NNNN is a compact frequency converter from Bosch Rexroth Indramat in the EFC Frequency Converters series. Installed between the incoming AC supply and an AC motor, it varies output frequency and voltage so machinery can match shaft speed to process demand. This supports variable-speed operation in fans, conveyors, pumps, and other general automation equipment. It is intended for compact panel installations where adjustable motor speed is needed without a large drive package.

For heavy-duty service, the drive can deliver 0.75 kW of mechanical output, and that rating is supported by a supply range of AC 200…240 V ±10%. A single-phase connection lets the unit operate from a standard power source without a separate transformer. The inverter uses Enhanced V/Hz control, which keeps voltage and frequency proportional so induction-motor torque remains stable across the speed range. The housing has an IP 20 rating, so the converter is intended for installation inside a control cabinet where live parts need basic touch protection.

Field integration is handled through Modbus messaging, and the controller uses a Flex-Control with Standard I/O layout so discrete signals can be wired directly to terminals. An internal filter for Industrial area, class C3 limits conducted emissions on longer motor and supply cables. Mechanical packaging is split between frame sizes B (1P) / C (3P), so the enclosure format stays consistent across single-phase and three-phase versions. Parameter access requires removal of the dust cover because the converter is shipped without a display. This arrangement suits installations that rely on external controls or a central HMI instead of a local keypad.
