Power supply module selection
The selection of a power supply module is made via the power curve of the DC link over time. The power curve results from the overlaying travel profiles of all connected axis modules.
Changing the assignment of cycles with respect to time strongly influences the load of the power supply module. If no time reference can be made, it is necessary to take a worst-case scenario into account.
Due to the complexity of the utilization curves, the calculation can only be performed using software. The SEW-Workbench software offers support for dimensioning.
If energy storage units are to be used in the application, additional customer requirements must also be known for optimum project planning. These include, for example, the expected operating hours, the ambient temperatures of the energy storage units, the expected cable lengths, and options to be provided for storage unit disconnection and discharge. SEW-EURODRIVE will assist you with the project planning of the energy storage units and will determines the ideal operating mode and storage size as part of project planning. The result of the project planning also includes a complete list of all parameters needed for subsequent startup.
