Product Description:

The EFC5610-45K0-3P4-MDA-7P-SVPNN-L1NN is supplied by Bosch Rexroth Indramat as part of the EFC Frequency Converters series. This adjustable-speed AC drive conditions mains power and delivers variable-frequency output for induction motors used in conveyors, pumps, and material-handling stations. Within an automation cell, it sits between the plant power bus and the motor terminals, translating control commands into regulated voltage and frequency so that speed, acceleration, and torque follow the required motion profile. This arrangement also helps the connected motor run more efficiently during partial-load operation and routine speed changes.

Electrical capacity is matched to heavy-duty machines, and the converter can supply 45.0 kW of mechanical power at the motor shaft when required. It is designed for networks that deliver 400 V AC nominally, and it supports a 380 to 480 V operating window within the permitted tolerance range. A three-phase input helps the DC link operate with balanced line currents, while the integral class C3 EMC filter reduces conducted noise in industrial environments. Cabinet integration is straightforward because the electronics are protected to IP 20, allowing mounting inside standard control panels without additional gasketing and helping separate the power electronics from accidental contact.

For functional safety and streamlined control, the unit offers STO, which removes drive torque without switching the mains, and motion commands can be issued over Modbus in multi-vendor systems. The internal algorithm relies on vector control (SVC), which uses current feedback to maintain stable torque during load changes and low-speed operation. Local setup is handled through an LCD display with potentiometer, giving operators direct access to basic adjustments and status information. The Flex-Control section with standard I/O and frame size I also provides connection points for auxiliary signals, making it easier to integrate interlocks, reference inputs, and simple machine-level control functions.
