14 Energy efficiency
Lenze BlueGreen solutions serve to execute energy efficiency calculations for dimensioned drives.
• A project comparison serves to compare and optimise the different mechanical concepts and
drive components with regard to their energy required.
• You can calculate the share of energy in the production costs and the energy emissions for CO
2
certificates of the European Union for the entire production line.
• Calculate the investment costs, cost schedules, cost rankings and the overall costs of the drive
system.
• The results of the energy efficiency calculation are approximate values.
• Contact the Lenze sales if you want to calculate the energy efficiency of the drive system un-
der real operating conditions.
• The energy efficiency calculation considers the most important losses in the drive system.
• Considered loss sources: Application, gearbox, additional drive element, motor, inverter, re-
generative power supply module, brake chopper and brake resistors, DC-bus operation.
• Losses of the following components are excepted: Engine fans, Motor fans, motor brakes, fil-
ters, mains chokes, cables, additional modules of the inverter, automation components.
• The losses of the application are based on the efficiency of the application entered in the DSD.
