Product Description:

The 10.G6.CDA-3910 is an inverter module produced by KEB for the G6 Combivert IO Inverters series. The unit converts a fixed-frequency three-phase mains supply into a variable output that regulates the speed of induction or permanent-magnet motors in industrial automation cells, conveyor lines, and material-handling stations. By combining control, braking, and filtering functions in one housing, it provides compact motor control without requiring separate external modules for those tasks.

The drive accepts a three-phase 400 V AC/DC input and draws a rated input current of 8.0 A under nominal load. It delivers a rated output current of 5.8 A at a continuous apparent power of 4.0 kVA. An internal braking transistor is paired with a maximum braking current of 7 A so excess regenerative energy can be dissipated through an external resistor. Analog or digital control signals are used to select the operating mode, and an air-cooled heat sink maintains thermal stability. The inverter's carrier frequency is factory set to 4 kHz and can be increased to 8 kHz when lower audible noise is needed. Overcurrent protection trips at 12.5 A, and the built-in EMC filter reduces conducted noise on the supply lines.

The power stage supports motors up to 2.2 kW, and the short-time limit current of 10.4 A covers acceleration peaks that exceed the continuous rating. Line protection is handled by a main fuse no larger than 16 A, and dynamic braking requires an external resistor of at least 120 Ω to stay within thermal limits. A certified safety function, STO, removes torque when triggered and supports applications that require integrated safe torque off capability. The enclosure is rated IP20, which means the unit has touch-safe openings but no sealing against liquids, so it is intended for installation inside a closed control cabinet.
