Product Description:

The EFC5610-75K0-3P4-MDA-7P-DRNNN-L1NN is a variable-speed frequency converter manufactured by Bosch Rexroth Indramat within the EFC Frequency Converters series. As part of the EFC 5610 model family, it receives fixed utility power and produces controlled AC output so induction motors can run at commanded speed and torque levels. In automated lines, the unit fits between the mains feeder and motion equipment, providing energy savings, soft starts, and process-driven speed adjustment without mechanical gear changes.

The drive accepts a nominal input of 400 V across a 380–480 VAC tolerance band and is wired for three phases, enabling it to deliver up to 75.0 kW of output in heavy-duty mode. Standard Vector Control regulates the air-gap flux so torque remains linear down to low-frequency operation. The standard control configuration, combined with the Flex-Control section and its integrated I/O, allows start, stop, and reference commands to be issued directly from panel switches or sensors. Network supervision is provided through Modbus, which gives PLCs register-based access to parameters. For conducted emission compliance, an internal EMC filter rated for industrial installations meets class C3 limits, reducing the need for additional line chokes.

In frame size J, the converter occupies a compact footprint that simplifies back-plate mounting while preserving cooling clearance. A front-panel LCD display with a potentiometer supports local setup, allowing parameter changes and speed adjustment without a laptop. Functional safety is covered by the integrated Safe Torque Off circuit, which cuts inverter firing pulses when the dual-channel input is asserted. The enclosure carries an IP20 rating, so the electronics are touch-safe yet require cabinet installation for dust or fluid exposure. The unit is part of product line 02 and shares terminal numbering and screw-clamp geometry with lower-power models.
