Product Description:

Bosch Rexroth Indramat manufactures the EFC3610-2K20-3P4-MDA-NN-NNNNN-NNNN, which is included in the EFC Frequency Converters series. This inverter accepts three-phase line power and produces a variable output frequency. It allows industrial motors to accelerate, decelerate, and hold a commanded speed to match process demands in automated production cells.

The drive’s nominal shaft capability is 2.2 kW, indicating the mechanical power it can deliver to a connected motor under continuous duty. To achieve that level, it draws a line current of 5.6 A, a figure used when sizing upstream protection and cabling. The drive uses a 3 AC input, so all power terminals must be supplied from a balanced three-wire circuit. Speed commands can be trimmed in increments of 0.01 Hz, allowing fine resolution when matching a fan or pump curve. An enclosure rating of IP20 means live parts are finger-safe, but the unit must be mounted inside a control cabinet for dust and moisture protection. The control board provides 2 analog inputs and 1 analog output for proportional references, plus 5 digital inputs and 1 digital relay output for run, fault, and preset selection. A dust cover with five diagnostic LEDs shows status without opening the panel. Physical placement is simplified by a height of 206 mm, a width of 95 mm, and mounting holes drilled to 4.5 mm diameter, so the chassis aligns with standard DIN backplates.

The converter has an installation weight of 1.9 kg, which keeps handling straightforward when fastening the 170 mm deep housing to the cabinet wall. Communication to supervisory PLCs is carried over Modbus RTU, enabling parameter writes and real-time readback through the network. Emissions are limited to the industrial environment limits of Class C3, which helps support overall electromagnetic compatibility in the panel. The full depth of 170 mm leaves room for airflow passages behind the heat sink so rated thermal performance is maintained even when devices are stacked in tight enclosures.
