Significance of the duty cycle
In addition to the frictional and gravitational forces, the duty cycle is decisive for the choice of
motor. The duty cycle contains information regarding the sequence of motion of the drive
axis and the machining forces that occur in the process.
The motion sequence can be specified as a distance-time diagram, velocity-time diagram or
acceleration-time diagram, see following figure.
In accordance with the following relationships:
the diagrams for the sequence of motion can be converted to one other.
