Product Description:
The EFC5610-1K50-3P4-MDA-7P-FCPNN-L1NN is a variable-speed frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. It serves as the active link between a three-phase mains supply and an induction motor, outputting a controlled waveform whose frequency and voltage are set by a PLC. This capability allows automated conveyors, pumps, and fan systems to start smoothly and match speed to real-time load requirements. By varying output frequency during ramp-up, the unit also helps reduce mechanical shock on connected driveline components during motor startup.
Rated for heavy-duty loads, the converter delivers 1.5 kW of shaft power while maintaining constant torque across the rated speed range. It accepts a supply of 400 V (AC 380…480 V -15% / +10%) on a three-phase network, so it integrates with standard industrial plant wiring. The embedded control algorithms rely on standard vector control (SVC), enabling stable motor flux orientation and rapid response to load changes without external sensors. Process data and parameter sets are exchanged over Modbus, giving the drive direct compatibility with common HMI panels and supervisory controllers. This control method helps the motor hold stable speed when conveyor loading or pump demand changes during operation.
The mechanical housing corresponds to frame size C, and the open slots and heat sink geometry support cabinet mounting while keeping the housing width within 200 mm. The protective enclosure is rated IP20, so the converter must be installed inside a control panel that prevents dust or finger ingress. For functional safety, the integrated Safe Torque Off (STO) circuit disables the power stage through dual-channel logic, eliminating residual motor torque during emergency stops. Compliance with EMC requirements for an industrial area, Class C3 environment is achieved by the built-in filter, which reduces conducted noise on the mains side. A Flex-Control section with standard I/O and an LCD keypad with potentiometer permits local operation, jogging, and diagnostics without external tools.
