Product Description:

The EFC3610-0K75-3P4-MDA-7P-NNNNN-NNNN frequency converter is produced by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. Within automated plants, it supplies a variable output to induction motors, enabling precise speed and torque adjustment for pumps, fans, and conveying equipment while drawing energy from a fixed industrial mains supply. This operating role makes it suitable for compact drive applications where stable motor control is needed without a separate motion platform.

The unit handles motor loads up to 0.75 kW in heavy-duty operation. It accepts a supply of 400 V AC, with an input range of 380 to 480 V and a tolerance of -15% to +10%, through three phases that match common factory power grids. Regulation is executed with Enhanced V/Hz control, which maintains a proportional voltage-to-frequency ratio to preserve torque at low speeds. For networked systems, a built-in Modbus interface transfers parameters and status to PLCs or SCADA hosts. The drive’s control section uses a Flex-Control layout with standard digital and analog I/O, so external limit switches, thermistors, or speed references can connect without expansion cards. This arrangement supports routine integration with plant signals while keeping everyday speed regulation inside the drive.

Mechanical installation uses frame size B, which sets the converter’s footprint, mounting holes, and standard heat-sink depth for cabinet layout. The enclosure carries a protection rating of IP20, indicating finger-safe openings and a requirement for placement inside a closed electrical panel. Conducted emissions are reduced by an integrated EMC filter rated for industrial area, class C3, keeping line noise within acceptable limits on long cable runs. Local interaction is performed through a standard LCD display with potentiometer; the display shows frequency, current, and fault codes while the potentiometer provides a quick manual speed set point. The converter ships in product line 02 with a standard control configuration. Front access to the keypad allows routine viewing and adjustment without reaching into the field wiring area.
