Product Description:
The 12.G6.CDB-3910 is a frequency inverter manufactured by KEB for the G6 Combivert IO Inverters series. It converts fixed-frequency three-phase power into a variable-frequency output that aligns motor speed with process demand, allowing tighter control of conveyors, fans, and positioning tables in factory automation. By integrating the power stage, logic, and safety elements into a single housing, the unit serves as a compact solution where cabinet depth is limited yet responsive torque regulation is essential. Designed for decentralized or cabinet-mounted use, the drive interfaces directly with upstream PLCs to execute velocity or torque commands while monitoring real-time load feedback.
The input section accepts a three-phase 400 V AC/DC input and follows the 400 V class designation. The insulated-gate transistors switch at 4 kHz, producing a finely stepped output waveform that minimizes audible motor noise. A built-in braking transistor dissipates regenerated energy during deceleration. Drive protection includes an instantaneous trip at 216% of rated current, with a separate function that stops conduction during severe overcurrent events. Local and remote commands reach the control board through an analog and digital interface, and heat is expelled by air cooling across the flat rear heat sink. The components have an ingress protection rating of IP20, and the unit uses housing style B for installation in shallow panels.
Overload capacity is provided by a short-term current ceiling of 180% of rated current, supporting rapid acceleration cycles without nuisance trips. Functional safety is provided through the hardware-based STO channel, which removes gate signals from the power stage on demand. The inverter maintains full output at ambient temperatures from 5 to 40 °C and at altitudes up to 2000 m above sea level; operation at higher altitudes requires derating. An internal filter attenuates conducted and radiated emissions, helping cabinets meet EMC limits while preserving compact wiring layouts.
