Product Description:

The EFC5610-1K50-3P4-MDA-7P-FCPNN-NNNN frequency converter is produced by Bosch Rexroth Indramat as part of the EFC Frequency Converters series and the EFC 5610 model family. It is a frequency converter that sits between the mains supply and an AC motor to provide variable voltage and frequency. This arrangement lets the drive adjust motor output to changing demand instead of running at full speed all the time. In automated plants, the unit regulates speed, acceleration, and braking torque so conveyors, pumps, and fans can follow process commands while reducing energy use.

The converter accepts a supply of 400 V (AC 380…480 V -15% / +10%) across three phases, giving balanced input power for industrial drives. In heavy-duty mode, it can operate motors up to 1.5 kW, and torque is regulated through Standard Vector control SVC to maintain stable performance during load changes. Communication and parameter access rely on Modbus, enabling direct links to PLCs without additional fieldbus cards. Direct network access through Modbus supports status exchange, command handling, and parameter changes from upstream control equipment. The product line is coded 02, and the control configuration is listed as Standard. A front-mounted standard LCD display with an integrated potentiometer permits on-panel frequency adjustment and alarm viewing.

The housing meets IP 20 protection, so live parts are protected against finger contact when the drive is installed inside a cabinet. An internal EMC filter rated for Industrial area, class C3 helps limit conducted emissions in industrial environments. The housing uses Frame Size C, which helps with cabinet layout and mounting space. Logic and I/O are handled by the Flex-Control with Standard I/O section, which provides six digital inputs, one analog input, and a relay output for local run, stop, and speed references. No integrated safety function is included, so any required emergency-stop circuit must be provided externally.
