<p>A synchronization priority setting means (3) selects at least one shaft (J1) from among a plurality of shafts (J1, J2, ..., Jn) and sets the speed of the shaft (J1) at a prescribed value as a reference speed and sets the speeds of the other shafts (J2, ..., Jn) based on the reference speed or the speeds of other shafts. A synchronization control means (2) drives the shafts (J1, J2, ..., Jn) at the speeds set by the setting means (3) based on a drive start signal from a timing monitoring means (1).</p> |
