The inverters are exceptionally quiet and compact thanks to state-of-the-art IGBT power semiconductors, fan speed control as a function of temperature and reduced volumetric flow at the nominal working point.
A rated switching frequency of 2 kHz, optimized pulse patterns and pulse frequency wobbling all help to reduce motor noise
Individual modules and power components can be replaced quickly and easily, which ensures a higher level of plant availability. The design of replaceable components is based on the principle that they must be quick and easy to change. In addition, the "Spares on Web" Internet tool makes it easy to tailor the spare parts that are available to the task at hand (http://www.siemens.com/sow)
Can be easily integrated in automation solutions by means of a standard communications interface on the Control Unit as well as a range of analog and digital interfaces
Simple commissioning and parameterization via the IOP Intelligent Operator Panel or using the STARTER commissioning tool on a PC
Preset software functions make it easier to tailor the inverter to the individual plant. For example, the key functions for controlling pumps are stored as a preprogrammed macro in the drive
Regarding EMC, the units are sub-divided into various zones, and as a consequence, they are extremely insensitive to disturbances and are very reliable in operation. Detailed measurements and simulations have been conducted to determine the ideal positioning of air guidance and heat dissipation partitions
Special measures used in the construction of the cabinets ensure that they remain mechanically durable over their entire lifecycle. All components, from individual parts to the ready-to-connect cabinet, undergo rigorous testing throughout the entire production process. This guarantees a high level of functional reliability during installation and commissioning, as well as in operation
