Product Description:

The EFC5610-2K20-3P4-MDA-NN-NNNNN-NNNN is a frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. It sits between a three-phase supply and an induction motor, adjusting output voltage and frequency so connected equipment can run at commanded speeds with less mechanical stress during starts, stops, and load changes. Because the drive varies motor speed instead of running only at fixed line frequency, it can better match process demand during ramping and steady operation. This makes the unit suitable for conveyors, pumps, and fan systems where stable motor control is needed and where a PLC or similar controller manages the larger machine sequence.

This model accepts a nominal input of 400 V AC, 380 to 480 V, which covers the common low-voltage industrial supply range without requiring a separate transformer. In heavy-duty operation, it supports motors up to 2.2 kW. A three-phase supply and output arrangement helps keep current balanced, while standard vector control SVC maintains motor flux and improves speed stability at reduced speed. Device-level communication is handled through Modbus, so external control systems can exchange parameters and diagnostic data over a common serial network.

The inverter is built in frame size D, so its mounting pattern and heat-sink depth follow that enclosure format. An integrated filter rated for industrial area, Class C3 helps limit conducted and radiated emissions in industrial installations. The housing is rated IP20, which provides finger-safe protection but still requires installation inside a suitable enclosure with ventilation. Control terminals use the Flex-Control with standard I/O arrangement, giving access to fixed digital and analog connections without add-on cards. The unit is supplied with a dust cover in place of a local keypad, and the control configuration is standard. It is also listed under product line 02 of the EFC 5610 family.
