Product Description:

The EFC5610-0K75-3P4-MDB-7P-NNNNN-L1NN is an AC drive produced by Bosch Rexroth Indramat for the EFC Frequency Converters series. It converts fixed-frequency line power into a variable output so automation systems can match motor speed and torque to changing process demand. Positioned between the plant mains and a three-phase induction motor, the converter supports conveyors, pumps, and material-handling axes while reducing mechanical shock during starts and speed changes. Because the output frequency is adjustable, the same motor can handle slower process phases and faster transfer moves without requiring a mechanical ratio change.

The inverter operates on a nominal input of 400 V (AC 380…480 V −15 % / +10 %), so it can connect directly to common industrial mains. In heavy-duty mode it supports motors rated to 0.75 kW, supplying continuous torque for small drives without thermal derating. Its power stage uses three-phase power, which balances line currents and supports smooth motor operation. Dynamic regulation is provided by Standard Vector control SVC, which maintains flux orientation and improves low-speed torque compared with open-loop V/Hz control. This control method also helps the drive respond more consistently when the load changes during operation. Conducted emissions are reduced by an integrated industrial area, class C3 filter, helping the unit meet noise limits in industrial installations.

A front LCD panel with a potentiometer provides local setup, and networked systems can exchange parameters over Modbus for remote supervision. The integrated safety layer provides Safe Torque Off (STO), which removes gate signals to the IGBTs so the motor cannot produce torque during a stop command or lockout condition. The unit uses frame size B, and the housing has an IP 20 Cold Plate design that transfers heat through the base to the cabinet backplate instead of into the surrounding air. This cooling arrangement helps limit heat buildup around nearby control components in compact enclosures. Its Flex-Control section and standard I/O allow it to fit typical standalone drive layouts as well as simple networked machine sections.
