Product Description:

The EFC3610-2K20-1P2-MDA-NN-NNNNN-NNNN frequency converter is produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. As a compact drive component, it converts fixed-frequency mains power into variable output voltage and frequency for asynchronous motors, allowing controlled speed changes in conveyors, pumps, fans, mixers, packaging equipment, and other general-purpose machinery. The unit belongs to the EFC 3610 product line and is intended for mainstream factory automation where basic open-loop motor control is appropriate. Its compact format suits cabinet installations that need motor speed adjustment without the added complexity of closed-loop feedback hardware.

Rated for 2.2 kW in heavy-duty service, the converter can operate small to mid-size induction motors in typical industrial duty. Its input accepts AC 200…240 V ±10% from a low-voltage supply, and the internal rectifier is designed for a single-phase supply, which simplifies connection in smaller panels. An integrated EMC filter qualified for industrial area, Class C3 helps reduce conducted emissions on the supply lines during operation. The housing has an IP20 protection class, so it resists accidental contact with larger solid objects but still requires installation inside a control cabinet for normal use.

Parameter access is provided through the RS-485 port that uses Modbus, allowing straightforward command, status, and monitoring exchange with a PLC or HMI. Drive regulation relies on Enhanced V/Hz control, a scalar method that maintains usable motor torque across the programmed speed range without encoder feedback. Application wiring is routed to the board identified as Flex-Control with Standard I/O, which supports standard run commands, direction control, and analog reference signals. Mechanical installation follows Frame size D, giving the unit a consistent mounting pattern and overall enclosure size within this frame category.
