07.G6.FDA-YM00 by KEB

The 07.G6.FDA-YM00 is a variable-speed inverter manufactured by KEB within the G6 Combivert IO Inverters series. It converts incoming three-phase mains power into a controllable output for induction or synchronous motors used in general automation, conveyors, and packaging lines. By modulating voltage and frequency, the unit supports closed-loop torque and speed regulation for modern machine control. This operating method helps the connected motor match process demand during acceleration, steady running, and controlled deceleration.

This model is fed from a 400 V AC three-phase supply and uses an integrated EMC filter that complies with EN 61800-3 C1/C2 categories. At the inverter output, the unit can deliver 2.6 A continuously, matching motors up to 0.75 kW while maintaining thermal margin. The power stage supports 1.8 kVA of apparent power, which helps the drive absorb short load changes without immediate protective intervention. Pulse-width modulation occurs at 8 kHz, a carrier frequency selected to balance switching losses with acoustic performance. Two relay outputs rated at 30 VDC and 1 A provide status signaling to external control circuits, and the serial interface supports local parameter access and diagnostics.

The control electronics are powered separately from the main bus by a 24 V DC feed that tolerates +20% to -15% variation and consumes 400 mA, allowing parameter access even when the mains is isolated. Internally, the inverter follows the incoming 50/60 Hz grid and synthesizes output frequencies from zero up to 599 Hz, which supports both low-speed operation and high-speed motor applications. Network communication is accomplished through EtherCAT, enabling deterministic cycle times for coordinated multi-axis systems. A separate RS232/RS485 diagnostic channel remains available for local access independent of the fieldbus, and the integrated C1/C2 filter helps keep conducted emissions within plant limits.
