Product Description:

The 13.G6.C3C-3A00 is a three-phase inverter module manufactured by KEB and assigned to the G6 Combivert IO Inverters series. It interfaces with 400 V industrial distribution networks and produces a regulated AC output that lets OEMs tune motor speed, reduce mechanical stress, and improve energy use on conveyors, pumps, or small machining stations. Internal IGBT stages rectify and modulate the supply so the unit occupies the central role of drive, protection, and diagnostic element in multiload automation cells.

Nominal operation centers on a three-phase 50/60 Hz mains supply, where the inverter accepts 400 V AC at a rated input of 17 A and stores it on a 565 V DC link. The processed energy is fed to the motor terminals as 12 A of sinusoidal current, providing a continuous apparent output of 8.3 kVA. To match various motor inductances, the power stage switches at 8 kHz, a frequency that balances acoustic noise with thermal loading. Protective logic interrupts conduction if line or load current exceeds 216 %, preventing semiconductor overstress while still accommodating brief torque surges. Standard corner frequency is 6 Hz, and during zero-speed holding the drive can deliver 100% continuous current or 180% short-term current without slipping.

The drive’s application envelope extends to induction motors up to 5.5 kW, given the stated 12 A output capacity. Fast fault detection disconnects the DC bus if voltage rises beyond 840 V DC, while a braking chopper activates at 780 V DC to absorb regenerative energy. Undervoltage cutout occurs at 240 V DC so control logic remains stable during supply dips. An insulation measurement of 2 MΩ between power circuits and chassis supports grounded-system safety checks before startup. For overload events lasting a few seconds, the short-time current ceiling is 180 %, offering the additional torque needed to free stalled loads without exceeding the overcurrent trip. The protection circuit separates braking, undervoltage, and overvoltage responses so abnormal DC-bus conditions are handled automatically.
