Product Description:

The EFC5610-45K0-3P4-MDA-NN-NNNNN-L1NN frequency converter is manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. It is a three-phase AC drive that varies output frequency and voltage to control motor speed in industrial automation. By adjusting electrical output to the motor, it can match machine speed to process demand instead of running continuously at full speed. This approach supports controlled acceleration and deceleration during operation. It can be used where motors must respond smoothly to changing production requirements in conveyors, pumps, fans, and similar machinery.

This model is built to sustain a heavy-duty motor load of 45.0 kW. The input is rated for 400 V (AC 380…480 V -15%/+10%) and is intended for three-phase power distribution. To limit conducted emissions, the integrated EMC filter is graded for Industrial area, class C3. The enclosure has an IP20 protection class, so the unit is intended for installation inside a control cabinet with clean airflow. Standard control functions regulate torque and help maintain speed accuracy during load fluctuations.

Field integration is handled through the onboard Modbus interface, which exchanges setpoints, status words, and diagnostic data with a PLC. The built-in safety function, Safe Torque Off (STO), removes torque-producing power to the motor without opening the line contactor. Command and feedback wiring terminate on Flex-Control with Standard I/O, which provides terminals for limit switches and analog references. Motor operation uses Standard Vector control SVC for speed and torque regulation. A dust cover replaces the local keypad, so routine operation is intended for network commands or a remote operator panel. This layout suits cabinet-mounted systems where local operation at the drive face is not required.
