14.2 Tips for optimising the drive systems
Generally the following applies:
• Avoid overdimensioning without extremely overloading the components.
• The longer the operating time of the drive, the greater are the saving effects.
Further possibilities for an energy-efficient dimensioning of the drive system can be found in the
following table.
Legend Possible dimensioning
 Supply / feed
• In DC-bus connection,
• with power recovery into the mains.
 Inverter with
• servo control
• low switching frequency,
• 2-switch modulation (e.g. Inverter Drives 8400),
• VFCplus eco control mode.
 Motor
• Use synchronous motor, IE2 motor or 120-Hz motor
• Utilise speed setting range, e. g. 87 Hz operation for standard motors
 Gearbox with
• a high efficiency,
• a low number of stages,
• a low input speed.
 Application with
• low friction,
• low inertia.
