Working clock-synchronous servo axle group coupling/decoupling involves defining axle group demand value with master position value sequence table, servo axle group demand values

摘要

The method involves defining a servo axle group demand value using a table of master position value sequences stored in a computer and associated servo axle group demand values so that after coupling, speed and angle synchronization of the servo axle group to the master position value sequence takes place. Angle synchronization after decoupling and re-coupling involves shifting the working clock by one or more whole working clock periods. An Independent claim is also included for an arrangement for implementing the method.
