In this respect, the cycle duration should not exceed 10% of the thermal time constant t
a longer cycle duration is necessary, please contact your local Siemens office.

Significance of the duty cycle
In addition to the frictional torque, you must also take into account the duty cycle when
selecting the motor. The duty cycle contains information regarding the sequence of motion of
the drive axes and the machining forces that occur in the process.
Motional sequence
The motional sequence can be specified as a rotation angle-time diagram, angular velocity-
time diagram, speed-time diagram, or angular acceleration-time diagram. The torques
resulting from the motional sequence (accelerating torque M
to the angular acceleration α and moment of inertia J, and are in opposition to the
acceleration.
Angle-time diagrams and speed-time diagrams can be converted to angular acceleration-
time diagrams α (t) in accordance with the following correlations:
