Multi-axis Servo System

Beckhoff announced that its AX8000 multi-axis servo system now offers oversampling technology. This feature enables multiple samples of process data within a communication cycle with an oversampling factor of up to 128 and the transfer of all data in an array via EtherCAT. In addition, new setpoint values can transfer every 62.5 μs from the motion controller in the Industrial PC to the servo drive, along with μs motor current scans. Measured variables can be recorded several times in the drive, and the controller can access the buffered values within one cycle. In this way, a chart in TwinCAT Scope View can provide higher resolution, for example. In addition, synchronization with other drives – with or without oversampling functionality – remains unaffected, the company says, due to the distributed clocks principle of the EtherCAT industrial Ethernet system.
