Product Description:

The EFC5610-1K50-3P4-MDB-7P-NNNN-L1NN frequency converter is produced by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. It is part of product line 02 and the EFC 5610 model subset. As a variable-speed interface between the mains supply and an AC motor, it regulates torque and speed for industrial automation tasks such as pumps, fans, and conveyors. By modulating output frequency, it supports efficient operation while helping reduce mechanical shock on connected machinery. This lets the motor follow process demand more closely during startup, speed changes, and steady-state operation.

It accepts mains voltage of 400 V (AC 380...480 V -15% / +10%) and delivers up to 1.5 kW in heavy-duty operation. The drive uses standard vector control SVC to maintain motor torque accuracy at low speed, and communication with higher-level PLCs is provided through Modbus for parameter access and basic control exchange. The inverter is supplied in frame size C, which gives it a specific mounting footprint and cooling surface. Its internal control section uses the Flex-Control concept with Standard I/O, so common command and signal wiring can be handled without extra interface hardware.

The cold-plate construction has an IP20 protection class, so the converter must be installed inside an enclosure that prevents direct contact with live parts while using the plate for heat transfer. An integrated industrial area class C3 EMC filter limits conducted emissions on the supply network and supports use in typical industrial electrical environments. The converter operates on a three-phase input that matches common plant power distribution. A front-mounted standard LCD display with potentiometer provides local parameter editing and a manual speed reference, and it also allows operating values to be viewed at the drive front.
