Data collecting system and method for analysing malfuction and control performance of multi-servo system

摘要

The present invention discloses a data collection system and method for analyzing failure and control performance of a multi-axis servo system. In the present invention, the main controller of a multi-axis servo system generates a fault signal or an alarm signal for the entire system, or an event that generates a fault signal or an alarm signal of the corresponding motor in the motor drive of each axis occurs, or under predefined conditions. When a specific event occurs, the data collection device stores the data from the time before the predefined time from the event occurrence to the time after the predefined time from the event occurrence, so that the failure and control performance of the multi-axis servo system You can more effectively collect data for analysis.
