FANUC multi-axis synchronous control and application in large servo press

The structure of large-scale servo press based on FANUC PMI-A CNC was introduced. For the multi-motor synchronization requirements, master-slave synchronous control and the electronic virtual spindle synchronization method were both adopted. the speed integrator replication function was also adopted for the large deviation of motor load. Through the parameter configuration and function verification on the 12 000 kN servo press, it showed that the electronic virtual spindle synchronization control effect was better than the master-slave synchronization control, and the speed integrator copy function can realize the motor load average. These functions can meet the needs of multi-axis synchronous control of large servo press.
