AXIS#​.FIELDWEAKENING​.LOOPBW

Description

AXIS#.FIELDWEAKENING.LOOPBW determines the field-weakening-loop’s bandwidthClosed In computer networking, bandwidth often refers to a data rate measured in bits/s, for example, network throughput. The reason for the connection of data rate with the term bandwidth is that the limit to the data rate of a physical communication link is related to its bandwidth in hertz when entering the above-base-speed region.


  • The field weakening control loop is a nonlinear loop and the bandwidth increases as velocity increases. Always allow for 50% increase in the bandwidth.

To correctly set the internal parameters of the field weakening loop, based on the commanded bandwidth, the following motor parameters must be set correctly:

Fieldbus Information

EtherCATClosed ***EtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs CoE and CANopen
