Product Description:

The 15.G6.CDC-35B0 power drive is built by KEB as part of the G6 Combivert IO Inverters series. This cabinet-mount inverter accepts three-phase utility power, modulates it through an IGBT bridge, and delivers a variable voltage and frequency output suited for induction or permanent-magnet motors. By supplying closed-loop or open-loop motor control, it helps production lines, conveyors, and process equipment achieve commanded speeds without mechanical gear changes.

On the power side, the inverter is designed for three-phase 400 V AC/DC mains, while logic electronics run from a 24 V DC control supply so parameter memory stays active during mains isolation. Two analog inputs and two analog outputs accommodate speed references, and 8 digital inputs support start, jog, and limit functions. The drive also offers two digital outputs plus two relay outputs for status signaling. A built-in braking transistor dissipates regenerative energy through an external resistor, and an internal EMC filter reduces conducted emissions. The STO circuit provides a safety shutdown function, and PWM devices switch at 4 kHz to balance acoustic noise with current ripple. Setup is done through remote software because no keyboard or display is installed.

Thermal management relies on air cooling, meaning ambient airflow through the heat-sink fins removes switching losses generated at the IGBT stage. During transient load spikes, the inverter can withstand an overcurrent of 180 % of its rated value before tripping, while its short-time torque reserve is capped at 150 %, permitting rapid acceleration without selecting a larger frame size. These overload windows are supervised in real time by the microcontroller, which applies the drive’s analog and digital control scheme to blend high-resolution current sensing with deterministic gate firing. By combining that mixed-signal regulation with the internal braking path, the module sustains consistent motor performance across varying duty cycles without external chillers.
