Product Description:

The EFC5610-5K50-3P2-MDA-7P-DRNNN-L1NN is a frequency converter produced by Bosch Rexroth Indramat for the EFC Frequency Converters series. It belongs to product line 02 within the EFC 5610 range and serves as the power stage between the plant mains and an AC induction motor. By programming output frequency and voltage, the unit lets speed, torque, and acceleration match varying load demands in automated conveyors, pumps, and material-handling stations. That variable output allows the connected motor to ramp smoothly, hold lower process speeds, and respond to changing throughput demands without abrupt current surges. This helps reduce energy use and supports smoother process control without mechanical gearboxes.

The electrical input window is 200 to 240 V AC, and the drive uses a three-phase supply so the inverter can operate motors with heavy-duty loads up to 5.5 kW. Conversion is handled by standard vector control (SVC), which supports constant torque at low speed without feedback encoders. The control section uses Flex-Control with standard I/O, and an integrated EMC filter rated for industrial area, class C3 limits conducted interference on supply wiring. A standard LCD display with an integral potentiometer on the front panel provides local setpoint entry and status viewing. The front interface can also be used for routine adjustments and for checking operating status during normal machine use.

The drive offers Safe Torque Off (STO) to remove motor torque through hardware circuitry when a protective device is activated. Field control and diagnostics are handled over Modbus, allowing parameter access from PLCs without optional gateways. The enclosure meets IP20, so the unit must be mounted inside a control cabinet. This housing level helps protect against accidental contact with internal parts, but it is not intended for direct exposure to dust or water. Its mechanical outline follows frame size F, which keeps mounting points consistent with other EFC units. Ready-wired terminals accept start, stop, and direction commands directly from automation controllers.
