Publication number: 20210115626Abstract: For operating a drive system or a papermaking machine, motion parameters such as a rotary speed of a motor are determined. From at least one of the motion parameters, a performance value or Key Performance Index is calculated in a motion controller and/or in a non-local computing unit. The performance value is derived from changes in the motion parameters or control parameters over time and displayed to operating personnel on a display. The performance value represents a control performance indicating a control speed responsive to a set motion parameter and thus an operating state of the papermaking machine.Type: ApplicationFiled: April 13, 2018Publication date: April 22, 2021Applicant: Siemens AktiengesellschaftInventors: RAGNAR ARNASON, MARTIN MEINARDUS, JÜRGEN MIELKE, UWE WITTENDORFER, GERRIT WOLF

Patent number: 4461999Abstract: A circuit for producing a periodic sawtooth signal comprising an oscillator which is directly synchronizable by synchronizing pulses and the natural frequency of which is approximately equal to the repetition frequency of the pulses in the synchronizing absence of synchronizing pulses. At a phase difference between the sawtooth signal and the synchronizing pulses which exceeds a predetermined value the supply of synchronizing pulses is inhibited and a frequency correction circuit is made operative, causing the natural frequency of the oscillator to change. When the said phase difference becomes smaller than the predetermined value the frequency correction is switched-off and the synchronizing pulses are applied to the circuit so that direct synchronization is effected.Type: GrantFiled: September 4, 1981Date of Patent: July 24, 1984Assignee: U.S. Philips CorporationInventors: Gerrit Wolf, Godefridus H.
