Siemens 6SL3126-1TE21-8AA4 – SIMOVERT Masterdrives VFD Drive

The Siemens 6SL3126-1TE21-8AA4 is an industrial frequency inverter (VFD) from the SIMOVERT Masterdrives family, designed for speed and torque control of three-phase AC motors. It supports advanced control modes (vector/closed-loop control), enabling precise speed and torque regulation, and includes protections for overload and short circuit conditions. Intended for control cabinet mounting — ensure adequate cooling and, if required by the installation, EMC filtering. Common industrial applications include conveyors, pumps, winding/unwinding systems and general machinery requiring precise motor control. Verify motor and supply compatibility and consult Siemens documentation for parameterization and protection settings before installation.
