Product Description:

The EFC5610-5K50-3P4-MDA-NN-NNNNN-L1NN is a drive module manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. Classified as a frequency converter in product line 02, it belongs to the EFC 5610 model series. The unit converts fixed three-phase mains power into a variable output, allowing asynchronous motors to be speed-controlled in pumps, fans, and material-handling stations across automated production lines. This operating method helps match motor speed to process demand without relying on mechanical throttling.

In heavy-duty operation, the converter delivers 5.5 kW of shaft power and is rated for a three-phase input at 400 V (AC 380 to 480 V, -15% / +10%), so it can connect directly to standard factory networks. Its internal regulator uses standard vector control (SVC) to maintain torque without encoder feedback. The Flex-Control section with standard I/O provides discrete and analog interfaces for routine control wiring. This arrangement supports integration with common plant signals without requiring extra interface hardware. Field communication is provided through Modbus, enabling the converter to exchange commands and diagnostic data with supervisory PLCs. Because no operator keypad is installed, a dust cover takes its place and shields the front electronics. Conducted emissions toward the mains are reduced by an integrated EMC filter.

Mechanical installation is based on Frame Size E, which keeps mounting dimensions consistent with other devices in this power class. The metal housing carries an IP20 protection class, which blocks fingers and similar objects but still requires cabinet installation for greater ingress protection. For personnel protection, the inverter integrates Safe Torque Off (STO), which removes motor torque during an emergency stop. The embedded EMC filter is certified for industrial area, class C3 operation, making the unit suitable for industrial power environments.
