Program Examples:Cyclic recording of single Axis
Contents
Introduction
The following example demonstrate how to record an external interference in single axis.
the example was written for a motor without load, in lab conditions. Spinning the motor in low velocity and after couple of seconds hold the motor by using external device to stop it.
Program flow
The program refer to axis that fail during motion.
The program set motion conditions for an axis and start recording motion data.
Under the conditions the user set, the program stop recording and stop axis motion.
