Converters SINAMICS G120D They have been developed to solve complex drive problems, in particular for use as part of conveyor systems. They control the speed indicators of asynchronous electric motors and implement all the necessary processes for this equipment, from simple operations to vector control and positioning. The modular architecture allows maximum flexibility in the installation and selection of functional units during the integration of the drive.
The compact converter housings have a low profile, as well as a high degree of protection from water and dust, which makes it possible to freely use this device outdoors. Microprocessor control and modern IGBT technologies combined with PWM provide a high-quality and reliable product with extensive functionality. Upgraded safety management system (Safety Integrated, Safety Integrated Drive).
Powerful software is included for easy commissioning and adjustment of drive parameters.
