The Control Unit (CU) with PROFINET interface and PROFIsafe profile extends the modular system of the SINAMICS G120 series of frequency converters. This means that the SINAMICS G120 series of converters can also be operated in automation and drives architectures with PROFINET, for which safety requirements exist. In addition, the G120 PM240 FS F power modules up to 132 kW will be available from May 2008.

The 1LE1 series of IEC low-voltage motors with aluminum housing features innovative technology in the EFF1 and EFF2 efficiency classes in the power range 0.75 to 22 kW. The EFF1 motors attain a high degree of efficiency by using copper rotors. Power consumption of the motors is low and they are also better for the environment. Whatever the efficiency class, all motors are equipped with the same housing which is extremely compact and especially suitable for applications involving pumps and fans.

The new series of FLENDER MOTOX geared motors was introduced at this year's Hannover Fair. This series combines the extensive range of time-proven Siemens motors with gear units from Flender. The geared motors can be supplied with helical, parallel-shift and bevel helical gears for the power range up to 200 kW. Versions with helical worm gears have an output up to 11 kW and motors with worm gears up to 1.5 kW. Depending on the requirements, energy-saving or explosion-proof versions are also available.
