19.6.7 Machine diagnosis function
This function estimates the friction and vibrational component of the drive system in the equipment based on
the data in the driver, and recognizes an error in the machine parts, including a ball screw and bearing. The
information of the machine diagnosis function can be obtained with the following objects.
