Product Description:

The EFC5610-160K-3P4-MDA-7P-DRNNN-L1NN frequency converter is manufactured by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. Within the EFC 5610 model range and product line 02, it serves as a variable-speed interface between the three-phase mains and an AC motor. In automated production cells, the unit modulates motor torque and speed to match load conditions and reduce energy consumption.

The converter operates from a nominal supply of 400 V (AC 380...480 V -15% / +10%), a window that covers common industrial power grids. It feeds output to three phases, allowing balanced current sharing in large induction machines. In heavy-duty mode, the drive supports up to 160.0 kW of motor power, so it can start and regulate high-inertia loads such as pumps or extruders. The embedded Standard Vector control SVC algorithm calculates flux in real time to maintain torque accuracy even at low frequencies. With an enclosure rating of IP 20, live parts are guarded against accidental touch when the unit is installed inside a switch cabinet. Frame size L matches the mounting height and depth used by other high-power members of the series. A standard control configuration is supplied, and a front-mounted LCD display with potentiometer allows local parameter entry without external tools.

Field integration is performed through Modbus, so drive status and setpoints can be exchanged with PLCs over a single twisted pair. Internal command processing uses Flex-Control with Standard I/O, combining digital terminals and analog references for coordinated motor control. For electromagnetic compatibility, the built-in filter is rated for Industrial area, class C3, which attenuates conducted emissions on long motor cables. When machine builders apply the optional Safe Torque Off (STO) input, the converter removes motor-produced torque in less than a millisecond.
