Beschreibung
Zusammenfassung:	The invention relates to energy saving in vacuum systems by means of a method and a controller enabling to consider the fluctuation in system-pressure of a system by determining a maximum system-pressure S2H and a minimum system-pressure S2h for each working cycle W C based on a determined target system-pressure p n and a pre-set system-pressure p 0 for the current working cycle W Cn (n = 1, 2, 3, ...). The method is especially adapted to fluctuations in system-pressure level of a vacuum system comprising a vacuum gripper tool.
