Product Description:

The EFC5610-7K50-3P4-MDA-7P-FCPNN-L1NN is a frequency converter built by Bosch Rexroth Indramat within the EFC Frequency Converters series. The unit converts fixed mains power into a variable output. This allows asynchronous and permanent-magnet motors to operate with controlled speed and torque in automated conveyors, pumps, and material-processing stations. By adjusting output frequency and voltage, it helps the connected motor match changing process demands without constant full-speed operation.

Communication with an upper-level PLC is handled through the Modbus protocol, allowing parameter access over a simple two-wire serial link. The command electronics are arranged in a Flex-Control with standard I/O section, so digital and analog signals can be wired directly without option cards. This layout supports direct connection of common machine control signals. Motor regulation is performed by standard vector control (SVC), providing closed-loop flux estimation for better low-speed torque than scalar drives. Operators adjust setpoints on a standard LCD display with a potentiometer, which supplies live status in text form for local operation and monitoring. To limit conducted emissions, an integrated EMC filter rated for class C3 for industrial areas is installed. The power stage accepts 400 V (AC 380…480 V –15 % / +10 %) three-phase input, matching typical industrial mains networks.

Frame size E sets the converter's mounting footprint and cooling channel layout. In heavy-duty mode, the drive can supply 7.5 kW of shaft power, making it suitable for medium-power motors used in fan and compressor duties. The integrated Safe Torque Off (STO) function disconnects gate signals to the IGBTs so output torque falls to zero without cutting the mains. Protection class IP20 offers a finger-safe housing inside electrical panels. The enclosure is intended for installation inside a cabinet where external guarding is already provided.
