Robotics powered by servo motors are in every aspect of manufacturing from the automotive to pharmaceutical industry. Although it is important to acquire a baseline and acceptance test for Fault Zone Analysis of new motors coming into a plant, it is also important to remember that because servo motors are very application specific, a process analysis test is also important to capture for future troubleshooting purposes. Process analysis using the PdMA EMAX technology utilizes an In-Rush style current envelope to reflect the variations in torque throughout a normal movement of the servo motor. Comparing the newest data to the baseline or like motor/application will give great insight to any anomalies that have developed.
