| Abstract |
The paper presents the features of hardware and software of a new series of servo and main drives. The series consists of digitally vector-conlrolled IGBT-inverters, matched to permanent-magnet synchronous motors or asynchronous motors. The system is especially designed to cope with the high performance and reliability requirements of modern machine tool drives. The fiberoptical SERCOS interface links up all drives and the superimposed numerical control to an overall machine control-system with distributed intelligence. On the drive control level of each inverter all state variables influencing the proccss are measured or calculated: torque, speed and position (with a high resolution encoder). Depending on the application all control loops, including the position control, can be closed in the drive itself or via the bus in the master controller. |
