A planetary wheel gear arrangement (13) is connected to a machine drive shaft and to a tappet drive mechanism. The planetary wheel gear arrangement can be switched for altering the rotational speed of the tappet drive arrangement. The planetary wheel arrangement has a first and second planetary wheel gear (12,12') coupled together. The first planetary gear has a first brake mechanism (9), and the second planetary wheel-gear has a second brake (10) which can be separately operated. Antriebsvorrichtung und Verfahren zur Steuerung einer Antriebsvorrichtung für eine Umformmaschine, insbesondere eine Umformpresse, mit einer Planetenradgetriebeeinrichtung, die ein erstes und ein zweites schaltbares Planetenradgetriebe aufweist, die miteinander gekoppelt sind, wobei die Antriebsvorrichtung durch wechslseitiges Schalten des ersten und des zweiten schaltbaren Planetenradgetriebes gesteuert wird.
