Product Description:

The EFC5610-7K50-3P4-MDA-7P-DRNNN-L1NN is a variable-speed frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. It is intended to regulate induction motor speed and torque in automated machinery, enabling energy-optimized operation across conveyors, pumps, and general-purpose drives on the plant floor. By adjusting output frequency and voltage to match process demand, the drive helps motors run smoothly during routine speed changes and varying load conditions.

Communication with upper-level controllers is available through Modbus, and commands are executed by the drive’s standard vector control (SVC) algorithm, which maintains stable flux even at reduced speed. This control method supports steady low-speed operation and helps the motor maintain usable torque when the load changes. The power section is designed for a supply of 400 V AC (380–480 V, -15% to +10%) delivered over a three-phase network, matching typical industrial mains services. A built-in EMC filter limits conducted emissions, while frame size E and product line 02 set the cabinet envelope for this unit. The control section uses a Flex-Control layout with Standard I/O, and protection is provided by an IP20 enclosure for installation inside closed electrical panels. The standard control configuration also supports parameter cloning through a removable keypad, which helps duplicate settings across identical installations.

Local interaction is handled through a standard LCD display with a potentiometer that provides parameter access and manual speed trimming without external tools. The keypad also allows direct viewing of operating values during local adjustment. For environments with high harmonic noise, the integrated filter specified as industrial area, class C3 helps keep conducted emissions within the intended range. In heavy-duty mode, the inverter delivers 7.5 kW of motor power, providing capacity for constant-torque loads during acceleration. A certified Safe Torque Off (STO) channel disconnects gate signals to the output stage, removing torque-producing power without requiring a separate contactor.
