Additional Information

The 6FC5348-0AA02-0AA0 is a component of the external interface. Other parts of the external interface include the three Ethernet interfaces with standard RJ45 sockets, the PROFINET, the US, and the 24 V power supply.  This piece of the interfacing, the dual fan/batter module, has a X190 designation and a 6- pin connecter type.  All these are important and necessary parts of the module. 

This exception component has several amazing functions.  This dual fan/battery module will successfully cool the CPU with two simultaneous fans, and in the case that the SuperCap is insufficient it can perform SRAM buffering.The control unit is an excellent component that helps to regulate and control the whole system, including the dual fan/battery module. With the Control Unit overseeing the function of the machine as a whole, it will be aware and adjust the use of the fan, accordingly, depending on the temperature inside the unit. A fan warning will arise if either or both of the two fans stop turning. Another warning to be aware of is “Fan faul,” which indicates that the software has failed to act in response in a minute’s time.

The need for and use of a fan is evident in this particular unit.  The fan is designed to jump into action if natural cooling action is not working effectively. The fan is designed to work as a component of a Sinumerik or Simotion series system. This 6FC5348-0AA02-0AA0 is engineered, as a part of the system, to be aimed at cooling the Control Unit.  If the Control Unit overheat the whole system is fundamentally at risk, and so the key role that this fan plays as a part of the mechanism as a whole should not and cannot be underestimated. 

This small yet crucial dual fan/battery module is so crucial that the Control Unit will fail to operate successfully in the absence of the dual fan/battery part.  Conveniently, a 3 V lithium batter can be put into the dual fan/battery component. The Battery is equipped also with a convenient a cable that is 4 cm long and is connected to the batter on one end and has a plug connector on the other end. 

If you are in immediate dire need of a dual fan/batter module, or in the case that you want to have an extra on hand in case of immediate need of a replacement, this is a great product, and may be just the one you need to give you piece of mind and keep your operation running smoothly.  In the case that you are replacing a dual fan/battery module, the procedures to do so can be found in the manual in the manual section on this product page.
