Product Description:

The EFC5610-15K0-3P4-MDA-NN-NNNNN-NNNN is a frequency converter manufactured by Bosch Rexroth Indramat as part of the EFC Frequency Converters series. Installed between the mains and a three-phase motor, it modulates voltage and frequency. This gives automated equipment adjustable speed, controlled torque, and smoother starts and stops while helping the motor match changing process demands. That operating method lets the drive adapt motor speed to process changes without relying on fixed-speed operation.

It interfaces with automation controllers over the Modbus serial protocol, so parameter sets and status words can be exchanged with standard PLC hardware. Inside, a control algorithm based on standard vector control (SVC) calculates current and voltage vectors to help maintain constant torque from zero to base speed. The power section accepts a 400 V supply that can vary from 380 V to 480 V with a -15% to +10% tolerance. In heavy-duty mode, the inverter can deliver 15.0 kW of mechanical output to the motor shaft. This supports demanding motor loads in applications that require steady output over a broad operating range. Conducted emissions are limited by an integrated filter rated Class C3 for industrial areas, which suits non-public networks. The housing provides IP20 ingress protection, so it must be installed in an electrical cabinet, and the front panel has no display because a dust cover closes the keypad opening to reduce contamination of the control electronics.

Mechanical integration is simplified by the drive's compact frame size F, allowing it to fit neatly with other panel-mounted components. The rectifier and inverter bridges are designed for three-phase input power, which helps balance line currents and reduce harmonic distortion. At the I/O level, the unit uses Flex-Control with standard I/O, which provides configurable digital terminals, analog references, and relay outputs for motor-run feedback, fault signaling, and external PID loops. This arrangement also supports integration with external run commands, reference signals, and simple process control functions.
