Product Description:

The 10.S6.K12-2100 is an AC servo drive manufactured by KEB and assigned to the S6 Combivert Servo Drives series. Designed for machine tools, packaging lines, and general motion cells, the unit delivers controlled three-phase power to synchronous or induction motors, enabling precise speed and torque regulation in automated stations. By integrating current control, field-oriented algorithms, and onboard feedback processing, it serves as the central power interface between the plant’s control network and the mechanical axis.

The power section connects to a three-phase mains supply of 400 V AC, draws a rated current of 8.0 A, and provides a continuous apparent power of 4.0 kVA. On the motor side, the inverter supplies 5.8 A of output current, while the DC link is stabilized at 565 V. Pulse-width modulation runs at a carrier frequency of 8 kHz to minimize torque ripple. Two analog inputs allow scalable speed or torque references, and eight digital inputs support limit switches, enable commands, or step functions. Under base load, the device dissipates 80 W as heat, which helps determine panel ventilation needs. The drive can energize machines up to 2.2 kW, matching small-frame servomotors used in indexers or linear actuators.

The drive has an IP20 protection rating, which means it has basic finger-safe shielding and must be mounted inside an electrical cabinet. During regenerative events, the internal brake chopper engages at 780 V and can conduct braking currents up to 11 A when the connected resistance is no less than 82 Ω. A fault is declared if the DC bus rises above 840 V or drops below 240 V, helping protect the inverter against semiconductor overstress or loss of control. These thresholds work with the chopper path to keep DC-link energy within acceptable limits during rapid deceleration or load reversal.
