step Description of the configuring activity
4. Selection of the SINAMICS Motor Module Refer to
catalog
5. Steps 3 and 4 are repeated for additional axes
6. Calculation of the required DC link power and selection of the SINAMICS Line
Module
7. Selection of the line-side options (main switch, fuses, line filters, etc.)
8. Specification of the required control performance and selection of the Control
Unit, definition of component cabling
9. Definition of other system components (e.g. braking resistors)
10. Calculation of the current demand of the 24 V DC supply for the components
and specification of the power supplies (SITOP devices, Control Supply Mod‐
ules)
11. Selection of the components for the connection system
12. Configuration of the drive line-up components
13. Calculation of the required cable cross sections for power supply and motor
connections
14. Inclusion of mandatory installation clearances
3.3.1.1 Clarification of type of drive
Select the motor on the basis of the required torque (load torque), which is defined by the
application, e.g. traveling drives, hoisting drives, test stands, centrifuges, paper and rolling mill
drives, feed drives or main spindle drives.
Gearboxes to convert motion or to adapt the motor speed and motor torque to the load
conditions must also be taken into account when selecting the motor.
You must know the following mechanical data in order to determine the torque to be supplied
by the motor:
● The load torque specified by the application
● Masses to be moved
● Diameter of the drive wheel
● Leadscrew pitch, gear ratios
● Frictional resistance data
● Mechanical efficiency
● Traversing distances
● Maximum velocity
● Maximum acceleration and maximum deceleration
● Cycle time
