VP = Vorpolieren = предварительное полирование

Там и про Fächerrad есть, и про VP в качестве маркировки пасты для предварительной полировки.

РАБОЧАЯ СКОРОСТЬ ВРАЩЕНИЯ

1. Process for running up/re-running up to continuous printing in a sheet processing printing press, particularly an offset sheet printing press, in which the sheets to be printed are fed from a pile of a feeder of the printing press connected via a switchable clutch with the printing press, wherein the feeder can be switched in at a low base rotational speed (VG) of the printing press, the rotational speed of the printing press after switching in the feeder is run up to a pre-set rotational speed (VZ; VP) and the printing begins following the running in of a first sheet into the printing press, characterised in that on switching on the feeder at the low base rotational speed (VG), the elements effecting the removal of the sheet from the pile remain switched off, that the printing press is run up to an intermediate rotational speed (VZ) lying above the base rotational speed (VG) and below the production rotational speed (VP) provided for the continuous printing, and that after achieving the intermediate rotational speed (VZ), the switching in of the elements effecting the feeding of the sheets from the pile is switched in and the printing begins following running in of a first sheet into the printing press.

Nachdem der Anleger zum Zeitpunkt t1 eingekuppelt wurde wird nun die Geschwindigkeit der Druckmaschine von der Grunddrehzahl VG wiederum durch entsprechendes Ansteuern des Hauptantriebs gemäß einer vorgegebenen Zeitrampe auf die Produktionsdrehzahl VP hochgefahren. Nach einer bestimmten Zeitspanne erreicht die Druckmaschine die vorgesehene Produktionsdrehzahl VP.

Очевидно, речь идет о сравнении или уравнивании скоростей двух упомянутых в вопросе узлов
