Product Description:

The EFC5610-132K-3P4-MDA-7P-NNNNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. It modulates the supply frequency applied to three-phase induction machines so that production lines, pumps, or fans can run at precisely commanded speeds and torques without mechanical gear changes. By converting fixed mains power into a variable output, this unit forms a central element in drive cabinets where coordinated speed regulation, energy savings, and electrical process control are required.

Under heavy-duty loading, the converter supports a motor rating of 132.0 kW. Its input accepts 400 V AC (380-480 V, -15% / +10%), and the design assumes a three-phase supply, giving balanced current flow into the DC link. Regulation is handled by standard vector control (SVC), which maintains motor flux and torque accuracy during speed changes. A certified Safe Torque Off (STO) circuit disconnects gate drives so mechanical motion stops without external contactors. The control section follows a Flex-Control layout with standard I/O, allowing hard-wired start, stop, and reference commands alongside fieldbus data. Users interact through a standard LCD display with an integral potentiometer, and the default configuration is standard, so no optional extensions occupy the internal option slots.

For networked plants, the drive speaks Modbus, permitting parameter access from PLCs or HMIs over a simple two-wire link. An integrated EMC filter rated for Industrial area, class C3 limits conducted emissions so additional external chokes are not needed in most cabinets. The housing meets IP20, so it must be mounted inside a dust-tight enclosure but needs no special gasketed doors. The mechanical footprint follows Frame Size K, which uses ventilation clearances common to this enclosure size.
